The Finite Difference Time Domain (FDTD) Method is used for full-wave electromagnetic (EM) simulations. FDTD is computationally intensive with performance depending critically on architecture-specific optimizations that have become more challenging given the rapidly changing architectures in modern high-performance computing platforms. We examine a templated meta-programming technique to implement...
An innovative approach for reducing grating lobes appearing when the inter-element spacing of an UWB linear array is greater than half-wavelength is presented. The main innovation of the proposed new design methodology is related to the fact that the positions of the array elements are left unchanged in the direction of the axis of the array (thus not affecting the gain of the pattern), while they...
The original layout of the microstrip branch-line 3-dB coupler with considerably smaller dimensions, compared to the conventional one, due to the use of a sequence of high- and low-impedance lines representing a lowpass filter is presented in this paper. Such filters have smaller longitudinal size than conventional microstrip line. The proposed design with a central frequency of 2000 MHz was simulated...
Wireless Power Transfer coil designs have been explored and two novel coil designs are presented in this paper. Controlling Specific Absorption Rate (SAR) and Leakage Electric Fields emanating from coils and antennas have been major issues. The two designs presented in this paper are applicable for the spiral as well as the solenoid coil designs. The self and mutual inductances, as well as the coupling...
