Analysis of Quasi-Optical Components for Far-Infrared Astronomy
This thesis is concerned with the development and analysis of quasi-optical components used in experiments to measure of the CMB in the terahertz and submillimetre wavebands. I have concentrated on corrugated horn structures in the Planck and QUBIC experiments. A precise analysis of the …

Electromagnetic Techniques for Analysis and Design of Ultra Sensitive Receivers for Far-Infrared Astronomy
… the behaviour of receivers and detectors for far-IR (far-infrared) astronomy and CMB (cosmic microwave background) applications, toward an optimum design for SAFARI (the Spica Far-Infrared Instrument) on the proposed space based telescope SPICA (Space Infrared Telescope for Cosmology and …

Towards Integrated Pixel Modelling
… cavity, and absorber) structures of future far-infrared instruments. Contemporary waveguide technologies increasingly rely on the exploitation of multi-moded behaviour and operation in higher frequency bands. In these scenarios a more comprehensive approach is required to correctly predict …
