This article presents a fully on-chip low-power low drop-out (LDO) voltage regulator dedicated to remotely powered wireless cortical implants. This regulator is stable over the full range of alternating current without the need of dedicated active circuitr ...
In this paper, a generalized form of telegrapher's equations for electromagnetic field coupling to buried wires is derived. The presented approach is based on thin-wire antenna theory. The effect of a dissipative half-space is taken into account via the re ...
The paper investigates the applicability of some closed form expressions for the ground impedance and ground admittance of buried horizontal wires (bare and insulated) for lightning or switching transient analyses based on transmission line (TL) theory. In ...
We demonstrate that it is possible to combine several small metallic particles in a very compact geometry without loss of their individual modal properties by adding a gold metallic film underneath. This film essentially acts as a "ground plane" which chan ...
This paper is aimed at analyzing the influence of the frequency-dependent behavior of the ground electrical parameters ( conductivity and ground permittivity) on the electromagnetic field radiated by a cloud-to-ground lightning return stroke. Both radiatio ...
A broad bandwidth and high gain rectangular patch antenna was specifically designed in this paper using planar-patterned metamaterial concepts. Based on an ordinary patch antenna, the antenna has isolated triangle gaps and crossed strip-line gaps etched on ...
A dual-polarized, broadband antenna made up of two single-polarized dipoles is presented. The antenna is mounted on a ground plane to produce a low-profile structure. Two fractal-like elements are used, but a very wide bandwidth is only achieved by making ...
Three antenna systems, composed of circular monopoles with different ground plane sizes, are studied. The transmission of an UWB pulse between two identical monopoles is analyzed. The omnidirectional properties of the UWB antennas are measured and simulate ...

In this paper, we present further improvements in the subdomain multilevel approach (SMA), one of the techniques used for fast full-wave analysis of large printed antennas and circuits. The time for filling the method of moments (MoM) matrix is improved in ...
This paper presents a numerical and experimental verification of an approximate but efficient integral equation technique for the scattering by apertures in conducting planes with finite thicknesses. The approach is based on a perturbation method and modif ...
