Using spreadsheet programs on personal computers for electromagnetic coupling calculations

Procedures have been developed for using spreadsheet programs on personal computers for performing electromagnetic coupling calculations. These procedures allows the EMC engineer to quickly analyze reasonably complex coupling problems. The spreadsheet computational technique emphasizes how electromagnetic energy flows from the source or culprit to the receiver or victim. Each step in the computational process is represented by a relatively simple, easily understood coupling model. This technique frees the EMC engineer from computational housekeeping and allows attention to be focused on the physics of the situation.
