This paper describes a full wave approach for analyzing planar interconnect structures, such as power distribution systems in printed circuit boards and multichip modules, using a tightly coupled combination of FDTD and SPICE. The technique enhances the present hybrid full wave circuit methods in terms of robustness and efficiency. The method is applied to a few sample problems to illustrate it...

This paper presents a new whole-body averaged specific absorption rate (SAR) estimation method based on the cylindrical fields scanning technique. The aim of this study is to achieve experimentally an estimation of whole-body averaged SAR in human models due to plane wave exposure using the radiation-field scanning technique. In this paper, the validity of the proposed methods is investigated u...

Folded slots are attractive for active arrays because of their broad bandwidth and simplicity. They have been used recently in a quasi-optical amplifier array. However, little is known about these antennas on thin substrates. The finite-difference time-domain (FDTD) method is applied to the analysis of cpw-fed folded-slot antennas. This paper compares the theoretical results and measured data a...

A conformal antenna array is analysed using an enhanced FDTD method. This antenna array is designed for use for in a channel sounder for characterising MIMO channels at UMTS frequencies, and (scaled to work at higher frequencies) may also be proposed as a MIMO antenna for wireless LANs. The FDTD model is shown to be extremely accurate for characterising important parameters of the array such as...
