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

정재파측정법과 Time Domain법에 의한 전파흡수능측정법의 비교 연구

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.
