Waveguide/resonant-disc circuits for millimetre-wave devices
Electronics Letters, 1982 Bias circuits using resonant discs have been employed for millimetre-wave transferred-electron (TE) diodes operating at their second or third harmonic frequencies in the V (50–75 GHz) and W (75–110 GHz) bands. It is shown that this type of circuit exhibits resonances at frequencies in the lower millimetre-wave range, corresponding to the fundamental ...

A millimetre-wave superconducting hyper-spectral device
RAS Techniques and Instruments, 2023 Abstract Millimetre-wave observations represent an important tool for cosmology studies. The line intensity mapping technique has been proposed to map in three dimensions the specific intensity due to line (e.g. [C ii] and CO) emission, e.g. from the primordial galaxies, as a function of redshift.
