Optimization of Advanced Multi-component Quasi-optical Systems

Advanced Quasi-optical (QO) systems with multiple refractive and reflective components are needed in a wide range of mm- and sub-mm wave applications (100 GHz - 1000 GHz) to meet demanding requirements in terms of wide operation bandwidths, compact footprints, and wide field of view. Designing such QO systems is one of the key enablers for the future security imagers, wide band communication links, THz sensing systems, and instruments for FIR astronomy.

Due to their relatively large size in terms of wavelength, analysis and design of such multi-component systems is not straightforward. We have previously developed a rapid and accurate sequential Geometrical Optics technique combined with an analysis in reception mode to optimise QO geometries for very specific scenarios.  In this MSc. project, we will extend this approach to develop an in-house design tool for optimising  advanced multi-component QO systems targeting a wide range of applications and requirements.

MSc Thesis Project

•  Expanding sequential Geometrical Optics plus field matching in reception techniques into an in-house design tool.

•  Applying the tool for synthesizing a multi-component QO system targeting a compact FIR imaging spectrometer.
