Abstract

In this paper, the authors present a study of the dependence of the field enhancement on geometrical parameters of the antennas and the optimization of these parameters to attain the largest possible enhancement. Intensity enhancements up to 10⁴ times the incident intensity are possible with semiconductor THz antennas. In particular, the THz scattering and near field enhancement by rectangular and bow-tie semiconductor antennas have been calculated using the rigorous two-dimensional (2D) Green integral formulation of the electromagnetic wave scattering.
