Everyday Analyses Using IEMCAP Models and Programmable Calculators

Abstract

A large number of EMI problems involve coupling from one emitter to one receptor, e.g., one antenna to another. Large computer programs, such as the Intrasystem Electromagnetic Compatibility Analysis Program (IEMCAP) are cumbersome to use for smallscope analyses. Programmable calculator programs are ideal for this task. This paper describes programs for the Hewlett-Packard 9820A calculator, based on IEMCAP models. The programs calculate wireto-wire, antenna-to-antenna, and antenna-to-wire coupling. Simplifications and special algorithms used to stay within the capabilities of the calculator are described.
