Abstract:
1. A terahertz (THz) detector assembly, comprising: a first dielectric substrate; an antenna array fabricated on said first substrate, said antenna array including a first capacitive plate portion; a second dielectric substrate; a sensor array constructed on said second dielectric substrate, said sensor array comprising a suspended platform including a second capacitive plate portion and a thermal sensor, said sensor array operative to transfer THz energy received by said antenna array to an electrical load via capacitive coupling and to convert the heat generated by said load to an electrical signal, wherein said capacitive coupling provides thermal isolation between said antenna array and said sensor array, and wherein said suspended platform is suspended by one or more holding arms connected to said second dielectric substrate, the one or more holding arms acting as springs allowing said suspended platform to move; and wherein said assembly is implemented by vertically joining said antenna array to said sensor array so as to establish one or more coupling capacitors made up of the capacitive plate portion of said antenna array and the capacitive plate portion of said sensor array.
