정재파측정법과 Time Domain법에 의한 전파흡수능측정법의 비교 연구

A Comparative Study on Measuring Methods of Absorption Characteristics for Electromagnetic Wave Using Standing Wave Measurement Method and Time Domain Method.

The goal of this research is to get a measuring system for absorption characteristics of electromagnetic wave absorbers in ferrite type which are lat grid-type special type etc. It is however very difficult to measure the absorption characteristics as in low frequency as in 30 MHz, To solve the problem therefore we propose a standing wave method and a measurement method in time domain using parallel striplines construct the measuring system and measure the characteristics of ferrite microwave absorbers in grid type using the proposed measuring system.
