The introduction of lung navigation systems in the clinical practice has enabled a transbronchial minimally invasive access to flexible microwave ablation catheters for the treatment of lung cancer lesions. These complex procedures are currently performed under Cone-Beam CT and require lung navigation system and bronchoscope. On bench lung models integrating tumor-mimicking targets for usability assessment are in demand due to the lack of representative in vivo models. In this paper, three tumor models made of minced bovine muscle, bovine tripe and ovine heart were integrated inside inflated ovine lungs and assessed in terms of radiopacity, required piercing force and dielectric properties. The impact of iodine to enhance radiopacity in the other desired model characteristics is also evaluated.

A Near-Field/Far-Field technique employing a prolate spheroidal modelling of the source is presented.The approach is devised for oblong antennas which can be accommodated within a prolate spheroid and can be applied to non-directive antennas or directive antennas on one far-field cut only. The tangential components of the electric field over the spheroidal surface are expanded by Prolate Spheroidal Wave Functions (PSWFs) so that the unknowns of the problem amount to be the representation coefficients. Such coefficients are related to the tangential components of the field measured on a cylindrical surface and are determined, in a regularized way, by a Singular Value Decomposition approach.The PSWFs are calculated according to the method devised by Adelman, Gumerov and Duraiswami.Numerical results presented.

Nowadays, innovative and disruptive new technologies, e.g., 5G, electric vehicles, and others, have given rise to increasingly challenging environment for electromagnetic interference (EMI) suppression, therefore, to overcome this issue new innovative solutions to provide electromagnetic shielding are needed. This paper aims to investigate, numerically, the design of a three-dimensional metallic electromagnetic bandgap (EBG) structure that employ an inverse woodpile cell in order to perform a highly effective shielding for frequencies up to 10 GHz, as well as to allow communication frequencies, selectively mitigating EMI in the electronic device from the external environment, and vice-versa. Our results have shown that the structure presents strong peaks of reflections in the region where frequency is below the cutoff frequency characterizing the 3-D EBG, furthermore, this structure may provide component-level shielding due to complete bandgap and may be well-tuned for vehicular EMC applications that must meet international standards.

A hypothesis that a simple glass microsphere excited by a point dipole located on its surface or in its close proximity creates an imaging beam in some sense similar to that created by a metamaterial hyperlens found the confirmation in our numerical simulations. The imaging beam can be created either by creeping waves or simply by rays emitted by the object refracting on the back side of the sphere. The first mechanism of imaging can be implemented by glass microspheres of modest sizes, corresponds to the coherent imaging and demands the lateral coherent illumination. The second and most important mechanism can be implemented by microspheres of larger sizes. It corresponds to the non-coherent non-resonant imaging. In this case we envisage several scenarios of the imaging. One of them corresponds to the case experimentally implemented by the group of M. Hong in 2011, and other scenarios still need an experimental check. In our COMSOL simulations we checked these scenarios partially, but one of them was implemented completely and the resolution about λ/4 in far fields was numerically demonstrated.

A laser combines wth target chamber fulfil a system of high power (PW) ultrashort (~20 fsec) laser beam. It heats the target inside the interaction chamber. The chamber is in vacuum of 10−7mbar and the interaction between the laser and the target causes both an electromagnetic pulse (EMP) and electrons to be emitted (~1012) from the target . The T-probe purpose is to supply read of the target current, which is flows in the system. The EMP disturbance can be characterized by number of differential equations and related parameters (based on equivalent circuit of the target probe). The delay parameters (τ1, τ2) in times characterize the EMP interaction (parasitic effects which are second components of EMP) with the chamber, laser and target, and time delay τ3 is related to employ coaxial cable. The investigation of our laser and target chamber system is based on non linear dynamic theory which investigate the behaviour through delay differential equations (DDEs) which is dependent on variable parameters. All of that for optimization of a laser and target chamber system parameters analysis to understand EMP disturbances. The analysis involves graphs of function of τ1, τ2, τ3.

Frame theory applied to source field decomposition facilitates the decomposition of an incident plane wave into a set of paraxial Gaussian beams. Spatial and spectral localization properties of such beams allow to bounce them through multiple reflections when reflecting surfaces are smooth and large enough as compared to wavelength. Gaussian beam spectral localization also yields dramatic reduction of the number of beams contributing to monostatic scattering cross section. An algorithm taking advantage of those properties is presented and applied to scattering by a set of blocks simulating an urban-like environment, with large dimensions as compared to wavelength. Numerical results will illustrate the method efficiency and will be compared to Fast Iterative Physical Optics results.

The ongoing effort towards understanding the physical principles underlying optomechanical forces is an active field of research that offers diverse applications in various fields of technology. The proposed physical model for the radiation pressure exerted on an achiral carbon nanotube (CNT), is formulated using the Maxwell stress tensor. Our model consists of a system of integral equations, describing the scattering pattern of an electromagnetic field (EM) for a single, finite-length, CNT in the THz frequency range. The obtained results from the proposed model, are presented for three cases: I) The optical force exerted on a CNT subjected to a surface EM-mode. II) The optical binding of two parallel non-identical CNT's III) The excitation of a radial breathing mode by the surface EM-mode in a CNT. Our current results can be implemented in the design of CNT-based ion and gas sensors, biosensors, field emission devices, and new types of metamaterials.

We propose a classical emulation methodology to emulate quantum phenomena arising from any non-classical quantum state using only a finite set of coherent states or their statistical mixtures. This allows us to successfully reproduce well-known quantum effects using resources that can be much more feasibly generated in the laboratory. Our results shed new light on an alternative operational meaning to non-classicality. We present a simple procedure to experimentally carry out quantum-state emulation with coherent states that also applies to any general set of classical states that are easier to generate, and demonstrate its capabilities in observing the Hong-Ou-Mandel effect, violating Bell inequalities and witnessing quantum non-classicality.

In the present work, we study, both experimentally and theoretically, the conductive hollow spheres’ electrical polarizability as a fundamental electromagnetic parameter that can be applied for the characterization of any individual non-magnetic object of micro- and macroscopic scale: atom, molecule, particle, etc. The polarizability of individual hollow conductive spheres of different diameters (2-5 mm) were investigated using a perturbed rectangular waveguide-based cavity in Ku-band (12-18 GHz). The simple analytical model for metaatoms’ polarizability calculations in the microwave range was proposed and verified. The obtained results demonstrate significant potential for using hollow spheres with controlled size and conductivity as metaatoms for microwave metamaterials design.

In this work we present a virtual reality machine-learning system for telehealth orthopedic treatment. Our system can recognize orthopedic abnormalities and the presence of pain. It is based on a widely used virtual reality system, combined with its sensors. We implemented an algorithm that can identify very accurately wrist and neck pain and can serve as a real-time remote system for rehabilitation doctors or physical therapists, as part of a virtual reality telehealth treatment program. Our algorithms synchronize the patient’s movement data with a dedicated data server. The system has an easy-to-use interface for analysis of the collected data. We achieved more than 90% success rates evaluating the presence of neck pain and wrist pain across given exercises for each of our volunteers. Our system can serve as the basis for a real-world telehealth, clinically operative machine.
