All-Dielectric Frequency Selective Surface for High Power Microwaves

Abstract

In this work, an all-dielectric frequency selective surface was developed for high power microwaves. By avoiding the use of metals, arcing at field concentration points and heating in the conductors was avoided. To do this in a compact form factor while still producing a strong frequency response, we based our design on guided-mode resonance (GMR). To make this approach viable for radio and microwave frequencies, we overcame three major challenges. First, conventional GMR devices have less than 1% fractional bandwidth and we extended this to 16%. Second, conventional GMR devices have a field-of-view less than 1 and we extended this to over 40 . Third, conventional GMR devices must be composed of hundreds of periods to operate, but our device operated very well with only eight. In this paper, we present our design and experimental results at 1.7 .

All-dielectric metamaterial frequency selective surface based on spatial arrangement ceramic resonators

“…With these advantages, all-dielectric FSSs come into being in recent years. Bertoni et al, 4 Park et al, 5,6 Magnusson et al, [7][8][9] Bossard et al [10][11][12] and Barton et al 13,14 make pioneer works and great contribution to the developing of all-dielectric FSS. In our previous work, all-dielectric metamaterial stop band, 15 pass band 16 and reconfigurable 17 FSS have been designed.…”

Study of the Unit Structure in Frequency Selective Fabric Fabricated by U-Shaped Velvet

“…The metal aperture-type FSSs transmit the electromagnetic wave around the resonance frequency [1]. In recent years, the FSSs have been investigated by many researchers about the structure of single-layer [2,3], multi-layer [4][5][6][7]or 3D [8][9][10] metal unit. Changing the design of electromagnetic materials, unit size, arrangement and other parameters, metal FSSs can obtain the specific resonance frequency, such as broadband, multi frequency, better angle stability, miniaturization or other characteristics.…”

A Compact and Stable Frequency Selective Surface for WLAN Applications

“…These elements can be of aperture type, patch type or an array of all-dielectric elements. The FSS structure can exhibit bandstop or bandpass characteristics, which depends primarily on the type and the geometry of the structure in one period called unit cell [1], [2], [3], [4].…”
