This paper presents a metamaterial design that acts as a strongly resonant absorber at terahertz frequencies. The design consists of a bilayer unit cell, allowing independent tuning of the electrical permittivity and magnetic permeability to maximize absorption. An experimental absorptivity of 70% at 1.3 terahertz is demonstrated, achieving an absorption coefficient of α = 2000 cm⁻¹. The metamaterial's low volume, low density, and narrow band response make it promising for thermally based THz imaging. The metamaterial is fabricated using a surface micromachining process on a semi-insulating GaAs wafer, with a 6 μm thick polyimide spacer. Experimental measurements show good agreement with simulations, confirming the high absorptivity at the designed frequency. The device is polarization-sensitive, which is beneficial for THz imaging to avoid "glint" issues. The narrowband absorptivity and geometric scalability of the metamaterials make them suitable for spectrally selective detection and potential applications in thermal detectors and imaging systems.This paper presents a metamaterial design that acts as a strongly resonant absorber at terahertz frequencies.
