Astigmatism-free Brewster lenses for terahertz applications

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...

Zusammenfassung:	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.
