The sub-terahertz (subTHz) and terahertz (THz) bands (0.1-10 THz) 1 present significant opportunities across a wide range of industrial and research fields 2. In this paper, we contribute to these ...
Sub-wavelength grating (SWG) metamaterials have garnered a great interest for their singular capability to shape the propagation of light. However, practical SWG implementations are limited by ...
