Miniaturized frequency selective surfaces (FSSs) have been intensively investigated because of the space limitation in practical applications, such as wireless communication system working at low frequencies. Loading lumped capacitor is an effective miniaturization method to achieve the unit cell size as compact as λ0/15 (λ0 refers to the resonant wavelength in free space) [1, 2]. But this approach...
The method based on the discrete approximate image theory to calculate Green's function for thin truncated grounded dielectric substrate has been proposed. Through assuming the truncated edges as perfectly magnetic conductors (PMC), the solution has been obtained by using the images caused from the multi-reflections of the magnetic walls. The simulated results demonstrate not only the validity of...
