Research of the New Structure of Reflection Symmetric Modal Filter

The paper considers the protection of radio-electronic equipment against ultrashort pulses (USP) by means of modal filters (MFs). The new structure of reflection symmetric MF structure is analyzed. It is reflection symmetric MF with an internal two-layer reference conductor. The results of a quasi-static and electrodynamic analysis of the reflection symmetric MF under influence of the USP, without and with taking into account the losses are presented. Consistency of results are obtained. The results are useful for further research, since the implementation of the reflection symmetric MF in such configuration is appropriate for further implementation.
