Circuit models for band pass filter of RF front-end system damaged by high power electromagnetic pulse

Summary form only given. In present days, the effect of high power electromagnetic(HPEM) threats become increased. This HPEM threats cause critical damaging to electronic equipment. There are two ways of electronic equipment damaged by HPEM pulse: front-door coupling and back-door coupling¹. Since front-door coupling is intended to transmit and to receive the electromagnetic wave, a lot more power is induced to it than back-door coupling and it is difficult to shield perfectly due to its purpose, transmitting and receiving electromagnetic waves. Because of these problems, it is necessary to study the damage and shield of RF systems affected by HPEM pulse.
