Abstract

A novel technique is shown for assigning electrical properties to geometries defined in a mechanical CAD tool environment. A special algorithm was developed that uses color code information and is able to assign parameters such as dielectric constant, metal resistivity, node name, terminating resistance values and signal source amplitude to arbitrary shaped bodies that are defined in a CAD drawing tool. A unified graphical user interface is provided to design engineers to draw and define a structure, and also convert it to a format that can be directly used for modeling of the electromagnetic field response using powerful full-wave solvers.
