A novel CPW-fed dual notched circular monopole UWB antenna for wireless body area network is presented in this paper. An advanced U shaped slot and an I shaped slot are loaded on the circular patch to filter C band, WiMax and WLAN. The simulated results indicate that the designed antenna has a good performance at filtering those unwanted frequencies. To test if it is still functioning well on wireless body area network applications, we build a 3 layers human body model located under the UWB antenna. The simulated results identify that this antenna can be used for wireless body area network applications.

The reduced basis method is a model-order reduction technique that converts the original system equations into smaller ones using a reduced basis set. This basis set is usually derived from a set of solutions of the system equation with different values of control parameters. If the system model changes affinely with the parameter values, a reduced-order model can be derived. In this abstract, we apply the reduced basis method to method of moments for quasi-periodic array modeling. With this method, a new basis set for a single element is constructed through an offline process. Because of the similarities among elements, the number of basis functions for each element can be much less than directing modeling from geometrical mesh. Numerical example shows that both the computational and memory efficiency is improved compared with direct modeling using method of moments.

The recent technology of intelligent systems have been used multiple sensors to assess real-time information of the internal system states and the environmental operating conditions. In case of sensor (s) transient fault, the disconnection of the readings caused to apply inappropriate actions. So, the needs for sensor fault detecting and estimating multiple sensor faults become an important process to optimize and enhance the system performance. In this paper, a robust analysis of multi-sensor architecture fault detection has been introduced to study different arrangement sensors architecture and detect the transient fault of each sensor. Then, a pseudo sensor enhancement method (PSEM) has been presented and investigated. The simulation results of different sensor architecture configurations without and with applying the PSEM have been introduced and analyzed to demonstrate the performance of the proposed method to meet the requirements for multiple sensor intelligent systems.

In this paper, a compact TE pass polarizer based on silicon-on-insulator (SOI) is reported and analyzed. The suggested design depends on asymmetric silicon coupler to separate the two polarizing states and hence the required polarizing state can be obtained. The proposed SOI TE polarizer can achieve -16.15 dB extinction ratio and -0.67 dB insertion losses with compact device length of 4.5 μm. Further, the introduced device is easy for fabrication and is compatible with standard CMOS fabrication process.

In the ACES 2015 meeting, the author presented a method for synthesizing array patterns using a matrix that relates element excitations with the lobe maxima of a desired pattern [1]. The method is applied here to the synthesis of both a Dolph-Chebyshev scanning array and one that has nonuniformly spaced elements.

Recently, it is very significant task to solve the problem of frequency hopping (FH) signals in the complicated Electromagnetic environment (EME) without prior information. There are many existing methods used to solve this problem but most of them need more computation as result of sparse information and used time-frequency analysis. In this paper, an algorithm based on blind signal separation (BSS) techniques to solve the problem of FH radar signals, the difficulty and the calculations of time-frequency domain are solved by tensor decomposition. Where, the proposed algorithm, exploits tensor decomposition to deal with the blind separation problem of FH radar signals. Also this algorithm can solve the problem without using any sparseness information. The efficiency of the proposed work is tested by Signal to Interference Ratio (SIR) and Mean-Square Error (MSE), as shown in the simulated results.

Within RF contested or degraded environments it is often necessary to establish a communication link using quickly deployable nodes. The need for a rapid set-up time can be accommodated if the node's antenna establishes itself upon deployment without the need for manual adjustment. One class of antenna that minimizes set up time is the self-righting antenna. This antenna is housed within the electronics of the deployable node. Once the node is placed, the antenna automatically uprights itself and establishes a link to other nodes in the communication link.

In this paper, the recent updates in the Multiple Multipole Program (MMP) analysis of photonic structures are introduced, with a special emphasis on the structures built in layered media. Along with the mathematical background of MMP, several numerical techniques including the scattering and eigenvalue analyses of photonic structures are introduced. Numerical examples are also included to demonstrate the advantages of MMP over other computational analysis tools, which will be further discussed during the talk.

Computational electromagnetic algorithms are indispensible to today's electromagnetic compatibility. However the nonlinear I/O modeling and its hybridized simulation with electromagnetic solvers were less addressed. In this paper, we discuss two major solutions we proposed for nonlinear I/O modeling. When the details of the circuit are given known, the SPICE circuit model can be employed in the simulation. However when the detail of the nonlinear I/O is not known, which happens often, a parametric macro model is first developed to replace the I/O before the hybridized characterization. The proposed techniques are mostly suitable for time domain based computational electromagnetics systems.

Most often, transmission and reflection properties and geometrical constraints (such as size) are the sole considerations in metamaterials design. Typically, power handling is of little concern as most applications are very low power. Here, we consider not only the complex transmission and reflection properties but also the magnitude of the electric fields in and around the structure when designing metamaterials for robustness in high power reflectarray applications.
