This paper reports on a preliminary characterisation of the complex permittivity of tissues within the oral cavity. In-vivo dielectric measurements were conducted on the lips and on five different areas of the tongue corresponding to different anatomical areas (ventral, dorsal, tip, left and right sides). The study included 25 patients having different ages and for each patient, three independent measurements were repeated for each tissue type. From this study, it has been observed that no statistical difference exists between the different areas of the tongue. However, there exists a statistical difference between the average dielectric properties of the tongue and lips.

IEEE Standard 149, Standard Test Procedures for Antennas, was last revised in 1979 [1]. Over the years, the standard was reaffirmed without any change and its validity for antenna measurements was re-established without a proper revision to account for state-of-the-art facilities and measurement practices. To initiate the revision of this standard, a project authorization request (PAR) was approved by the IEEE Standards Association and a working group (WG) was formed. After several years revising and updating different clauses, the revision tasking is nearing completion. In this paper, we describe and comment on the changes to the document.

The term Internet of Things (IoT) refers today to the rapidly growing number of energy-limited wireless end-node sensor devices that interconnect over the internet and are remotely monitored and controlled. IoT is the main enabler for smart cities and as a consequence, it impacts various smart city applications like air pollution monitoring, traffic and parking control, waste management, and more. In most cases, the sensors are spread over the city and are wirelessly connected to one or more gateways. The gateway receives the collected sensor’s data and transfers it up to a server located at the backbone. Achieving optimal connectivity and availability between the end-node devices and the backbone is challenging and requires deploying multiple device-to-gateway configuration schemes. This paper describes and explores several such schemes that incorporate most communication needs in smart cities.

We demonstrate a parallel and efficient mutli-domain scheme for Density Functional Theory (DFT) calculations of large molecular systems. The system is divided into sub-domains and the electrostatic potential produced by the charge density of each subdomain is calculated in a parallel manner. We show that our scheme leads to a linear scaling (instead of cubic) for the calculation time while keeping the same accuracy. This is demonstrated for a couple of systems with two molecules.

Sixth generation wireless communication promises extremely high data rates, exceptionally low latency, and extensive use of an intelligent fog/edge platform including storage, communications, control and processing resources. This fog/edge platform will provide scalable and elastic distributed processing, communications flow management, and application support capabilities. An extended, more distributed SDN (software defined network) is likely to be an important element of this environment, enabling local picocell clients to more efficiently share processing and communications resources. This distributed SDN, with a local SDN controller handling local needs such as handoffs between picocells with very low latency and networked with distant SDN controllers for wide-area communication and information retrieval needs, will mediate the QoS for both highly interactive local applications and large volume streaming and downloading. The distributed SDN will facilitate access to application processing and locally stored data in the fog/edge platform and keep track of networking transactions and resource use. This concept of a distributed SDN coupled with network edge computing and data storage will support the entrepreneurial development of new network modalities and applications meeting the needs of network operators, service providers, and end users. This introductory paper, including a vehicular control simulation example, suggests the possible shape of an intelligent network edge incorporating a distributed SDN for the future 6G network. Keywords— fog/edge; SDN; 6G; distributed network control

We present a method for the numerical evaluation of 6D singular integrals appearing in Volume Integral Equations. It is an extension of the Sauter-Schwab/Taylor-Duffy strategy for singular triangle-triangle interaction integrals to singular tetrahedron-tetrahedron interaction integrals. This general approach allows to use different kinds of kernel and basis functions. It also works on curvilinear domains. Our approach is based on relative coordinates and splitting the integration domain into subdomains for which quadrature rules can be constructed. Further, we show how to build these tensor-product quadrature rules economically using quadrature rules defined over 2D, 3D and 4D simplices. Compared to the existing approach where the integral is computed as a sequence of 1D integrations significant speedup can be achieved. The accuracy and convergence properties of the method are demonstrated by numerical experiments.

The implementation of non-specular reflection, generally referred to as perfect anomalous reflection, has been the realm of complex periodic metasurfaces consisting of multiple, painstakingly-designed meta-atoms. It has recently been shown that similar effects can be obtained from a basic periodic surface (BPS) with arbitrary properties, coated with several uniform dielectric layers which serve as a multimodal anti-reflective coating (MARC). In spite of its simplicity, the BPS-MARC combination can be easily designed to suppress all components of the discrete propagating Floquet-Bloch (FB) spectrum except the one in the design direction of interest. We show herein that the design direction of the reflected beam can be controlled by simply shifting the MARC relative to the BPS with the aid, for example, of a piezoelectric actuator. Such control enables dynamic beam switching from one radiation angle to another with almost-perfect efficiency. The MARC layers for this purpose are designed analytically and verified by full-wave computations, thus providing a new and conceptually simple method of efficient wave control in real time, highly useful for signal rerouting and multiplexing in reconfigurable antenna systems.

This work presents a derivation of the Newton-Raphson method, treated here as the Quasi-Newtonian (QN) algorithm. The QN has the same proprieties as the traditional Newton-Raphson method for extreme seeking, but due to a different manipulation of the Taylor series expansion, the method becomes a second-order method instead of a first-order method. Hence acquiring a fast convergence. That characteristic is explored in the performance of the Perturb and Observe algorithm for maximum power point tracking of photovoltaic systems. At this work, the QN is used not only to analyze the slope of the PxV curve of the photovoltaic system in order to choose the perturbation direction inserted by the Perturb and Observe algorithm (P&O) but to calculate the value of the perturbation as well. The simulation results have shown a fast-tracking of the maximum power point (MPP) and a small steady-state error when compared to the classical P&O algorithm.

The paper presents a metamaterial based LTCC compressed Luneburg lens antenna for wireless communications. The antenna is designed at 60 GHz to utilize the unlicensed mm-wave spectrum available for short-range high-data-rate communications. The gradient index compressed Luneburg lens antenna is designed using the quasi-conformal transformation optics method. The design of the antenna is fully compliant with the standard LTCC process with a high-permittivity host material. The diameter of the antenna is 19 mm and the thickness is less than 2 mm. The peak antenna gain at 60 GHz of 16 dBi is demonstrated. Beam scanning capacity is demonstrated with 1 dB scan loss within ±25 degree field of view.

A metasurface reflector that supports two-dimensional beam steering is essential for switching between users and bypassing obstacles to create a quasi-line-of-sight in fifth-generation wireless communication. Polarization considerations become very important when two-dimensional beam steering is desired. In practical beam-steering uses, the assumption that the users' polarization and the metasurface reflector polarization are the same is invalid. The beam steering performances of the metasurface reflector were analyzed as a function of the polarization angle between the users and the metasurface. This work shows that up to medium values in the polarization angle differences between the users and the intended metasurface reflector polarization, the beam steering performance is maintained in terms of gain, losses, and sidelobe level.
