Abstract

A high-power-capacity transmitting and receiving structure (TRS) is proposed. It has the ability of transmitting the GW-level high power microwave from the microwave sources with the horizontal polarized TE11 mode and receiving the microwave signal from the target with the orthogonal polarized TE11 mode. It is realized by the cooperation of a polarization-isolation-structure (PIS) and a two-way circular TE11 mode to rectangular TE10 mode power divider. Simulation shows that from 9.65 to 9.71 GHz, its power capacity is more than 3 GW at the transmitting format. The transmitting and receiving channel have an isolation of 60 dB which can prevent the receivers connecting to the receiving channel suffering from breakdown. The insertion losses for the transmitting and receiving format are both less than 0.03 dB.

Highlights

In recent years, With the development of high power microwave, more and more devices for microwave generation, microwave transmitting, and microwave radiation have been concentrated and successfully achieved.[1,2,3,4,5,6,7,8,9] Various microwave generation and transmitting devices are combined and working for the directional microwave systems
The transmitting and receiving structure (TRS) can transmit the GW-level high power microwave generated from the high power microwave sources with the horizontal linear polarized circular TE11 mode
When the TRS works at the transmitting format, the maximum surface E-field appears at the inserted metal plates on the YOZ plane and is approximately 1.4 kV/m when the TE11 (y-axis) is excited at port 4 with an incident power of 1 W

INTRODUCTION

With the development of high power microwave, more and more devices for microwave generation, microwave transmitting, and microwave radiation have been concentrated and successfully achieved.[1,2,3,4,5,6,7,8,9] Various microwave generation and transmitting devices are combined and working for the directional microwave systems. These systems can only work at the transmitting format. Simulation shows that the TRS features with high-power capacity, low insertion losses, and high isolation between the transmitting and receiving channels
