A Novel Ultra-Miniaturized Angularly Stable Frequency Selective Surface for L-Band Shielding Applications

International Journal of Antennas and Propagation
This paper presents a novel ultraminiaturized frequency selective surface (FSS) for L-band electromagnetic shielding applications. A basic square loop incorporated with folded arms in the top layer constructs the single-layer FSS design.

Closely spaced tri‐band frequency selective surfaces based on split ring slots

Electronics Letters, 2016
A tri‐band frequency selective surface (FSS) with close band spacing based on split ring slots for y‐polarised incident waves is investigated. The close band response is obtained by reducing the strong mutual coupling between the closely packed ...

Graphene-based polarization insensitive rasorber with tunable passband

Results in Physics, 2019
In this paper, a frequency-selective dual-polarization rasorber with absorption-transmission-absorption response is presented. The transmission window could be tunable when the chemical potentials of graphene loaded on the proposed rasorber are changed ...

Using WCS-FDTD Method to Study the Plasma Frequency Selective Surface

IEEE Access, 2019
The plasma is very useful to design the dynamically tunable Frequency Selective Surface (FSS) because of its tunable property. But it is difficult to simulate the plasma FSS by using the conventional finite-difference time-domain (FDTD) method, because ...
