A full-wave analysis of lenses for THz detectors purposes

In this work an analysis of power density inside various types of lenses is presented. Properties of structures commonly used in THz detectors have been verified using a full-wave EM simulations. Two alternative implementations of EM solvers have been considered. Possibility of replacing spherical-b...

Summary:In this work an analysis of power density inside various types of lenses is presented. Properties of structures commonly used in THz detectors have been verified using a full-wave EM simulations. Two alternative implementations of EM solvers have been considered. Possibility of replacing spherical-based structures with more sophisticated elliptical lenses were considered as well, showing similar properties.
