Abstract-Terahertz antenna electronic chopper
In this paper, we present an electronic circuit used to bias a photoconductive that generates The working principles and the design process for the device are discussed in detail. The and shape of the for a built device are considered. Furthermore, their impact on a terahertz pulse and its spectra is also examined. The proposed implementation is simple to build, robust and offers a real improvement over THz instrumentation due to the frequency tuning. Additionally, it provides for galvanic isolation and ESD protection.
