This work deals the characterization of a PEM fuel cell by the impedance spectroscopy method. A test bench is set up to allow measurements by the method of impedance spectroscopy under different current values. An Open Cathode Stack Pragma Industries fuel cell system is composed from 20 cells. A fuel cell modeling is based on the electrical elements. We used the method of « least square » to determine the parameters of the model based on measured values. The model is simulated in Matlab/Simulink.

In recent years, there is a rapid growth of wireless sensor networks mustered in different areas such as military, agriculture, surveillance, etc. WSNs are extremely necessitous for securing network protection. However, awful critical attacks of different kinds have been documented in these networks by many researchers. Sybil attack is one of those attacks in which a legal node is converted into a Sybil one which is a replica node with a different personality using a similar ID. In other words, Sybil attack occurs when a sensor node or base station assumes multiple identities by changing its MAC and IP addresses or other identity information. This attack mainly influences routing protocols and operations like voting, data aggregation and reputation. This paper proposes a dynamic and accurate method for Sybil attack detection and prevention. This method, combining Random Password Comparison (RPC) with Message Authentication and Passing method (MAP), will progress data transmission in the network and enhance the throughput.

In this paper, an UWB Tapered Slot Vivaldi Antenna (TSA) is presented. The proposed TSA is optimized in order to increase the bandwidth and ensure a good impedance matching at low and bandwidth frequencies while respecting the low profile. The overall size of simulated antenna is $45times 40times 0.8 text{mm}^{3}$. This antenna is designed in order to be used in bio medical application and some other radar based microwave imaging.

This paper presents a comparative study of a rectangular and circular patch antennas above the AMC structure, operating on two 2.4 GHz and 5.8 GHz frequency bands for WLAN applications. This structure is entirely made using textile materials. The results of simulations and measurements are presented to compare the performance of the two antennas. CST Microwave Studio is used to design and compare the performance of antennas. Based on the results found, it has been found that the rectangular patch antenna has a better performance compared to the circular patch antenna. And the proposed antennas have a good performance/size ratio compared to antennas exiting in the literature.

Implantable electronic devices are constantly evolving at an astonishing pace, supported by the technological breakthroughs of fields such as microelectronics, packaging, and integration techniques. The reduction of the implants' size is of paramount importance for their usefulness and development of new applications and therapies. However, state of the art biomedical devices often have their minimum volume limited by their power modules, i.e., battery and/or antenna. This paper presents a solution to significantly reduce the volume of an implantable device featuring wireless power transfer. This is achieved by resorting to a WPT method that allows implantable antennas to become considerably smaller. Simulated and experimental results determine that a three-fold decrease in antenna length is made possible resorting to multimode wireless power transmission technology. Such solution allows to deliver the same power to a smaller device while maintaining the same SAR level considered for standard WPT solutions.

This paper proposes a novel digital predistorter (DPD) for 2⨯2 nonlinear multiple-input-multiple-output (MIMO) transmitters. It is intended to compensate for the nonlinear distortion and the memory effects generated by power amplifiers (PAs) in addition to the crosstalk effects. The novel polynomial DPD performs comparably to the state-of-art Generalized Memory Polynomial for Nonlinear Crosstalk model (GMPNLC), while requiring much less coefficients. However, it exhibits much higher performances compared to Generalized Memory Polynomial for Linear Crosstalk (GMPLC) DPD for the same problem size.

This paper presents novel compact dipole antennas based on forward-coupling configuration of multilayer ring resonators (MRR) structure. The antenna consists of two conductive square open loops. The frequency of operation can be varied through the coupling between the two rings. This is achieved by changing the distance between the two radiating elements. Hence, these types of antennas are simply tunable. The structure is so versatile that a class of new antennas can be developed using this technique. The radiation pattern is bidirectional with a peak gain of 2.8 dBi. A good impedance matching and return loss better than 35 dB are obtained. Simulations have been carried out and the S-parameters, VSWR and radiation patterns are presented.

In this paper, we present the design of a small antenna with bidirectional radiation pattern and high gain for RFID reader application. This antenna, which has a very simple structure, is composed of three pairs of S-shaped meander line. The antenna is designed, fabricated and measured to operate at the SHF band (2.4-2.485 GHz). The tested results are in good agreement with those of the simulations. The proposed antenna has the advantage of high gain of 7db in both directions with a volume equal to 106 mm ⨯ 19 mm ⨯ 0.9 mm, which makes it easy to integrate in RFID readers and a good candidate for RFID smart parking applications.
