Protection of critical buildings, plants, and infrastructures against physical and cyber attacks is attracting more and more attention as governments and citizens become more aware of the problems that would arise if such facilities were attacked. Nonetheless, current security systems are not sufficient to guarantee an adequate level of protection. The goal of this paper is to propose a new concept of security system relying on multiple sensor technologies (e.g., radar, RFID, EO/IR cameras) for the protection of critical infrastructures against both physical and cyber attacks and for the intelligent reconfiguration of the infrastructure telecommunication network in the case of attack, so as to permit communication and operability continuity also during and right after the attack.

Microwave hyperthermia demonstrated its efficiency in several domains of medicine [1-6]. However this method has several limitations which can damage the healthy neighborhood. To increase the potential of this method and to avoid this problem, we suggest to create a special area consisting of the tumor injected by the lossy and nontoxic dielectric material: the recinoleic acid oil which has many advantages [7]. In this paper, we present a theoretical approach to demonstrate the advantage of using a lossy material with high dielectric losses in order to increase the temperature of the cancerous cells only. This approach is confirmed by measurements of the complex dielectric permittivity for recinoleic acid oil and for water in a large band of frequency [50 MHz-10 GHz]. Finally, we compare the results and conclude.

In this study, we illustrate the design and implementation of a wideband microwave small-signal amplifier composed of mixed elements. The design is based on Simplified Real Frequency Technique (SRFT). A design of low power amplifier circuit is completed and its simulations are performed in success. The circuit is designed with lumped elements, however, some of the lumped elements are converted to distributed elements for their convenience in production. In this way, a mixed element wideband microwave amplifier comprised of input/output matching networks with lumped and distributed elements has been formed. Layout work and also post layout simulation is given with satisfying results.

An all-metallic plano-concave zoned lens based on the fishnet metamaterial is designed and experimentally demonstrated at the V-band of millimeter waves. By applying the zoning technique the volume of the lens is reduced considerably up to 60% compared with a complete profiled lens. The lens is designed to work as a near-zero-refractive index medium (n=-0.25) at f=56.7GHz (λ0=5.29mm ) demonstrating an experimental focal length of 8.79λ0 and a full width at half maximum (FWHM) of 0.67λ0 with good agreement with simulation results.

Positioning techniques based on cellular networks are gaining more attention thanks to their accuracy and availability in multiple environment compared to GPS signal which face a big difficulty to reach them. Those techniques can be enhanced with adaptive filtering process, In this paper we will try to introduce the chosen positioning method to work with then apply two different type of filters to compare their performances.

Sensor nodes located in the vicinity of static sinks deplete rapidly their energy due to higher data relaying load. Consequently, this will result in congestions, data losses as well as a decrease in WSN lifetime. To overcome this problem, the concept of mobile sink was introduced in several works. In this paper, we propose an efficient data collection scheme using mobile sink that moves along a deterministic route and retrieve data stored in rendezvous nodes. To alleviate the problem of data delivery latency, rendezvous nodes move for a definite distance in parallel with the base station, in order to remain the longest possible within the sensing range, and upload the maximum amount of data. Our approach takes also into account the priority of data in the delivery process. Sensitive one has to be delivered first. Our scheme achieve a balance between energy saving and data collection delay.

This paper presents the broadband power amplifier design based on characterized behavior of the active device. Compared with other broadband design techniques, this approach is not limited to waveform manipulating; hence, multi octave performance is achievable. GaN HEMT package and die device models are used to verify this approach showing high efficiency performance over very large bandwidth. Simulation results show PAE of higher than 60% over 0.5-4 GHz for die and higher than 50% over 0.3-3.5 GHz for package device models.

In this paper, we investigated the radiation properties of novel planar monopole antenna with half-circular perturbations for ultra wideband (UWB) application. The proposed antenna, designed on low cost substrate material FR4, consists of a simple rectangular radiating patch with two half-circular cuts and a partial ground plane with a number of half-circular protuberances and cuts. The antenna is designed to operate from 1.85 GHz to 16.8 GHz and to achieve reflection of more than 10 dB. Good impedance matching, radiation pattern characteristics and constant efficiency are obtained in the frequency band of interest.

A triple-frequency compact monopole antenna with coplanar waveguide (CPW)-fed structure is presented in this paper for PCS 1900, WiMAX and WLAN applications. The proposed antenna, which consists of a rectangular radiation patch with L-shaped slot and an inverted L-shaped stub extending from the ground plane. By engraving an L-shaped slot on the rectangular radiation patch, the antenna can excite two resonant modes (WiMAX and WLAN). The third resonant mode is introduced by extending an inverted L-shaped stub from the ground plane (PCS 1900). The designed planar monopole antenna has a compact size of only 17×30×1 mm3 including the ground plane. The simulated -10dB impedance bandwidth at the first band (lower frequency, fr1=1.91 GHz) is about 180 MHz, for the second band (middle frequency, fr2=3.52 GHz) is about 650 MHz and at the third band (upper frequency, fr3=5.45 GHz) reaches about 1.45 GHz, which cover the PCS 1900 standards (from 1.85 to 1.99 GHz), the 3.5/5.5 GHz WiMAX standards and the IEEE 802.11a 5.2/5.8GHz WLAN standards, respectively. Furthermore, nearly omnidirectional radiation patterns, reflection coefficient and gain over the operating bands have been obtained.
