Electromagnetic Simulation to Determine Mesoscopic Dielectric Particle Parameters for Optimal Terajet Effect

This paper reports on optimization of the parameters, by mean of electromagnetic simulations to obtain the values of the parameters that permit optimal conditions for terahertz (THz) radiation detection using the terajet effect generated by inserting a cuboid-shaped mesoscopic dielectric particle in the optical path at in the front of the rectifier. The obtained results show that the length of edge of the cuboid is the key parameter that conditions the performance of the detection system. A substantial gain is obtained under optimal conditions.
