Abstract

Accurately resolving features that are small with regard to the basic spatial cell used throughout a finite-difference time-domain (FDTD) code has been of interest for the past 10 to 15 years. An examination of the layer problem is provided. There are numerous cases that require a rigorous analysis of the field behavior within the material. Obvious important examples include coatings designed to trap waves for stealth applications and propagation within multilayer circuit boards. These cases are examined here using an orthogonal, locally nonuniform mesh embedded within a uniform mesh based on the Yee formulation. The specific applications considered are the Salisbury screen and crosstalk on printed-circuit boards.<>
