In this paper, an algorithmic framework for cost-efficient design optimization of miniaturized impedance matching transformers has been presented. Our approach exploits a bottom-up design that involves translating the overall design specifications for the circuit at hand to its elementary building blocks (here, compact microstrip resonant cells, CMRCs), as well as fast surrogate-assisted optimization...
A computationally efficient technique for design optimization of UWB antennas has been presented. Our approach adopts feature-based optimization (FBO) concept where the computational speedup is achieved by reformulating the design specifications in terms of suitably defined response features. Because the dependence of the feature point coordinates on geometry parameters of the antenna is much less...
We present a graphics-processing-unit (GPU) OpenCL implementation of the multiline through-reflect-line (TRL) algorithm of vector-network-analyzer (VNA) calibration. We obtained about 40× of speed improvement on a middle-end GPU as compared to a single-threaded C/C++ implementation. This speed improvement leads to a significant acceleration of VNA-measurement Monte-Carlo uncertainty analysis, making...
The ubiquity of WLAN networks bears inherently a risk of generating considerable interference level. Measurements have been obtained to demonstrate that densely, though randomly deployed Access Points cannot operate at maximum bit rates due to mutual interference. A simple non-collaborating algorithm has been proposed and verified under carefully controlled measurement conditions providing a proof...
Article relates to the use of innovative root finding algorithm (on a complex plane) to study propagation properties of microwave and optical waveguides. Problems of this type occur not only in the analysis of lossy structures, but also in the study of complex and leaky modes (radiation phenomena). The proposed algorithm is simple to implement and can be applied for functions with singularities and...
