Open Access research which pushes advances in bionanotechnology

Strathprints makes available scholarly Open Access content by researchers in the Strathclyde Institute of Pharmacy & Biomedical Sciences (SIPBS) , based within the Faculty of Science.

SIPBS is a major research centre in Scotland focusing on 'new medicines', 'better medicines' and 'better use of medicines'. This includes the exploration of nanoparticles and nanomedicines within the wider research agenda of bionanotechnology, in which the tools of nanotechnology are applied to solve biological problems. At SIPBS multidisciplinary approaches are also pursued to improve bioscience understanding of novel therapeutic targets with the aim of developing therapeutic interventions and the investigation, development and manufacture of drug substances and products.

    Abstract

    An output coupler for a W-band high power wideband gyro-amplifier has been designed, manufactured and experimentally measured. It consists of a high performance sin2-parallel corrugated horn integrated with a broadband multi-layer window. The major design requirements are that the horn/window combination must have an input return loss lower than -30 dB over a 10 GHz bandwidth, provide a high quality output beam pattern, and operate under ultra-high vacuum conditions. The coupler converts a circular waveguide TE11 mode into the free space Laguerre Gaussian LG00 mode over the frequency band of 90–100 GHz with a measured return loss of between -30 and -40 dB and a simulated Gaussian coupling efficiency of over 99% at 94 GHz.
