A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part One

Solving Maxwell’s Equations for real-life situations, like predicting the RF emissions from a cell tower, requires more mathematical horsepower than any individual mind can muster. These equations don’t give the scientist or engineer just insight, they are literally the answer to everything RF.

“These requirements cover digital alarm communicator system units for use in central-station burglar-alarm systems, proprietary burglar alarm systems, police station connect burglar-alarm systems, residential burglar-alarm systems, residential fire warning systems, and home health care medical alert systems.”
