전자파/적외선 다중파장 흡수체의 설계와 초고주파 특성에 관한 연구 = A Study on Design and Microwave Characteristics of a RF/IR Multispectral Absorber

다국어 초록 (Multilingual Abstract)

In this paper, a design for a radio frequency(RF) and infrared(IR) absorber with metasurfaces is discussed inmicrowave frequency bands. The RF absorber includes double layers of metasurfaces to operate in S- and X-bands.
Effects of sheet resistance of the metasurfaces and thicknesses of dielectric supporting layers on reflectionresponses are investigated. An IR stealth layer incorporates an array of conductive grids with slits to reflect IRsignals but to transmit RF signals and visible rays. Periodicity of the grids and slits is studied for transmissionresponses in the X-band and a surface area ratio. Reflection responses of the RF/IR multispectral absorber arefound to be lower than -10 dB and -16 dB in the S- and X-bands, respectively, from full-wave simulation.
Finally, the RF/IR multispectral absorber is fabricated and its reflection responses are measured to verify designedperformance.
