Electric field enhancement computation for integrated detector of THz range

Abstract

One of most promising detectors for THz range is the hot electron bolometer on basis of semiconductor compound HgCdTe [1] .Experimental sensitivity is greater than theoretical prediction for such device. The most credible hypothesis is that metallic contacts to the detector play the role of antenna, which is greatly increasing an electric field in the active element. The main probable evidence of this is a strong frequency dependence of the system response similar with those for simple dipole antenna.
