Narrow strip above ground plane transmission line formulation in the FDTD algorithm [PDF]

open access: yes, 2004
A number of thin wire formalisms for use in the FDTD method have been published over the years. One such formalism was published by Holland and Simpson (IEEE Trans., EMC-23, no. 2, pp. 88-97, 1981). Later, Ledfelt (Ph.D.

The CGM and the FDTD for SAR studies [PDF]

open access: yesProceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002
In the study of electromagnetic radiation effects over dielectric bodies, effective numerical methods are needed. At present, there is a lack of tools for measuring these effects and due to the huge growth of microwave devices, like cellular radio telephones working close to the human body, it is necessary to develop accurate numerical methods for ...

Electromagnetic analysis of complex 3D PEC structures using a stabilised CPFDTD algorithm [PDF]

open access: yes, 1996
It has been shown that, with a simple modification, the contour path FDTD (CPFDTD) scheme can be stabilised while still being accurate for structures with a complex geometry containing tilted planes, smooth curved surfaces and right-angle bends. This has
