The paper introduces a rigorous methodology for predicting RF-to-DC conversion in power harvesters. The results of a full-wave EM simulation of the harvesting antenna are rigorously handled by EM theory to produce a Norton equivalent circuit of the antenna in the presence of an incident field. In turn, this allows a full nonlinear analysis of the rectifier to be carried out, thus providing an accurate...
A circuit-equivalent frequency-domain three-dimensional electromagnetic simulation for package structures is proposed. A robust and passive susceptance-element based model order reduction is applied to the governing equation for accelerated simulation and proof-of-concept is shown with the examples of power-ground structure simulations.
In this paper, CAD models of the input admittance of RC interconnects are discussed. To this aim, properties of RC circuits are exploited to show that the input admittance of RC wires is approximated very well by that of a low order RC circuit, as opposite to the timing modeling of RC wires. In particular, 1st- or 2nd-order equivalent circuits are shown to be sufficient for fast and accurate estimations...
A full-wave parametric analysis of a straight-to-bent microstrip line coupling has been performed and an equivalent circuit of the structure has been proposed. The circuit is composed of lumped elements modeling the reactive phenomena and the spurious emission caused by the excitation of the higher order modes at the microstrip discontinuity. The numerical results show that the coupling phenomena...
