A Study on the Measurement of Absorbption Characteristics for Ferrite Electromagnetic Wave Absorbers Using Parallel Stripline.

평형스트립라인을 이용한 페라이트계 전파흡수체의 특성측정에 관한 연구

The goal of this research is to get a measuring system for absorption characteristics over the frequency band with 30MHz to 1, 000MHz concerning the ferrite electromagnetic wave absorbers, for example, grid-type and sintered flat type, etc. It is, however, very difficult to measure the absorption characteristics as in low frequency as in 30 MHz. In this research, therefore, we propose a standing wave method using parallel striplines, fabricate the measuring system, and measure the characteristic of ferrite microwave absorbers using the proposed mea-suring system.
