—A new technique, the steepest descent-fast multipole method (SDFMM), is developed to efficiently analyze scattering from perfectly conducting random rough surfaces. Unlike other prevailing methods, this algorithm has linear computational complexity and memory requirements, making it a suitable candidate for analyzing scattering from large rough surfaces as(More)
A programmable wireless identification and sensing device is powered through energy harvesting and a software-defined RFID reader provides the means to investigate optimization approaches for RFID systems. ABSTRACT | The next generation internet will be the internet of things (and not just of computing devices like PCs, PDAs); this is presumed to be enabled(More)
Boundary element methods are being successfully used for modeling parasitic effects in cutting-edge circuit design. The dense system matrix generated therein presents a time and memory bottleneck. Fast iterative solver techniques, developed to address the problem, suffer from convergence issues which become pronounced for large number of right hand sides as(More)
Simulation of distributed electromagnetic effects of electrically large structures is no longer a luxury but a necessity in the accurate prediction of modern day circuit performance. In this regard, integral equation based methods have steadily gained in popularity but suffer from the time and memory bottlenecks arising from the resultant dense matrix. Fast(More)
