New Terahertz receivers at for Earth remote sensing

Research Project, 2024 – 2026

The main objectives of the project are to design and simulate two dual-polarisation integrated receivers operating at 874 GHz and 1200 GHz, for future compact small-satellite or cube-sat space missions for remote sensing. The work to be performed within this project is: - The designs and simulations of Terahertz x2 multiplier (output frequency of 440GHz & 650GHz) - The designs and simulations of two Orthomode transducer (OMT) probes (874 GHz & 1200 GHz) - The designs and simulations of the integrated Terahertz Sub-harmonic Mixers’ MMIC with OMT probes (874 GHz & 1200 GHz). - The designs and simulations of two spline horn antennas (874 GHz & 1200 GHz) - The designs and simulations of the two receiver's radiometric performances (874 GHz & 1200 GHz) - Manufacturing of all mechanical parts required - Assembly and test of all commercial components purchased for the testing of the two proposed receivers - Breadboarding activity with manufacture and measurements of the OMT dual-polarisation concept Results will be state-of-art performances of Schottky diodes receivers operating at 874 Ghz and 1200 GHz. The OMT breadboarding will gives state-of-the-art cross-polarisation discrimination at 874 GHz and 1200 GHz. Manufacturing of all mechanical parts and assembly of commercial components will be done within the project.
