Doctoral Student: Modules for THz heterodyne array receivers

• Oct 2019 - Sep 2022

Study the intermediate frequency (IF) impedance (up to 10 GHz) of a Terahertz Hot-Electron-Bolometer (HEB) mixer under its working conditions (cryogenic temperature). Study a 2 x 2 reflective phase grating beam divider to distribute local oscillator source for THz heterodyne array receiver at 1.3 THz. Assemble and test a receiver for antenna to observe the universe based on the spectrum of hydrogen gas (at centre frequency of 1420 MHz) in Hands-On Universe European Project.
