Abstract

We report on the simulation and experimental demonstration of Brewster lenses in the terahertz range. These lenses can be operated under the Brewster angle, ensuring reflection-free transmission of p-polarized light in a broad spectral range. The excellent focusing capabilities are verified by focus plane measurements using a fiber-coupled terahertz time domain spectroscopy system.
