Terahertz High-Q Absorber Based on Holes Array Perforated into a Metallic Slab
In this paper, we theoretically analyze and design a dual-narrowband terahertz (THz) absorber based on a hole array drilled into a metallic slab. A very high-quality factor (<i>Q</i>) is achieved at both of the resonance frequencies. A circuit model-based approach is developed for the an...
