Application of BLT equation to electromagnetic interaction of high power microwave

The electromagnetic interaction with electric devices caused by high power microwave(HPM) is now much concerned. The BLT equation can solve some problems of electromagnetic interaction. This paper firstly introduces the formulations of the BLT equation and the parameters of the equations. Secondly it extends the conventional BLT equation through studying a simple HPM interaction model. Finally it provides a numerical example to analyze the interaction responses arising from HPM. The results show that the extended BLT equation can evaluate the propagation of the electromagnetic energy along the conductors and the electromagnetic field propagation in the space.
