Terahertz Broadband Absorber Based on a Combined Circular Disc Structure

Terahertz Broadband Absorber Based on a Combined Circular Disc Structure

To solve the problem of complex structure and narrow absorption band of most of today′s terahertz absorbers, this paper proposes and utilizes the finite element (COMSOL) method to numerically simulate a broadband absorber based on a straightforward periodic structure consisting of a disk and concent...
