버섯형 구조에 형성된 표면 패치 사이의 집중 저항기 매트릭스가 짧은 쌍극자 센서의 2차원 배열로 작동하는 2차원(2-d) 전기장 분포를 모니터링할 수 있는 메타표면 흡수체가 개발되었습니다. 본 논문에서는 XNUMX차원 푸리에 분석을 이용한 평면파 스펙트럼(PWS) 기법을 이용한 수치계산을 통해 메타표면 흡수체에 입사되는 구형파의 흡수 및 반사를 분석합니다. 흡수체 표면에 입사된 구형파의 전자기장은 다수의 평면파로 확장되며, 각각에 대해 TE 및 TM 반사 및 흡수 계수가 적용됩니다. 그런 다음 모든 평면파 장을 합성하여 반사 및 흡수된 장의 공간 분포를 얻습니다. 계산의 상세한 공식이 설명되고, 계산된 필드 분포는 쌍극자로부터의 구형파가 메타표면 흡수체에 조명될 때 시뮬레이션 및 실제 측정을 통해 얻은 것과 비교됩니다. PWS 기술은 흡수체 위 및 주변의 구형파의 정확한 필드 분포를 얻는 데 효과적이고 효율적이라는 것이 입증되었습니다. 이는 EM 소스 주변의 구형파장 분포를 흡수하고 측정하기 위해 메타표면 흡수체의 성능을 평가하는 데 유용합니다.

Abstract: A metasurface absorber capable of monitoring two-dimensional (2-d) electric field distributions has been developed, where a matrix of lumped resistors between surface patches formed on a mushroom-type structure works as a 2-d array of short dipole sensors. In this paper absorption and reflection of a spherical wave incident on the metasurface absorber are analyzed by numerical computation by the plane-wave spectrum (PWS) technique using 2-d Fourier analysis. The electromagnetic field of the spherical wave incident on the absorber surface is expanded into a large number of plane waves, for each of which the TE and TM reflection and absorption coefficients are applied. Then by synthesizing all the plane wave fields we obtain the spatial distributions of reflected and absorbed fields. The detailed formulation of the computation is described, and the computed field distributions are compared with those obtained by simulation and actual measurement when the spherical wave from a dipole is illuminated onto a metasurface absorber. It is demonstrated that the PWS technique is effective and efficient in obtaining the accurate field distributions of the spherical wave on and around the absorber. This is useful for evaluating the performance of the metasurface absorber to absorb and measure the spherical wave field distributions around an EM source.
