Millimetre and FIR Broadband Quasi Optical Devices
Jodrell Bank Centre for Astrophysics, Alan Turing Building, School of Physics and Astronomy, The University of Manchester, Oxford Road, Manchester M13 9PL, UK
We present a set of techniques and materials we are currently developing which enable very broadband and highly effective optical devices in the spectral region from 20 GHz to 20 THz. Many of these devices have already been employed in terrestrial, airborne and space based telescope systems.
