Paper Abstract

In this paper we demonstrate the capability of non-spherical dielectric objects to generate terajets ‒ similar to the photonic nanojets ‒ at Terahertz frequencies. We investigated numerically three geometries with non-usual shape and compared them with a common dielectric sphere. The focusing terajet performance was evaluated and one of the proposed geometry shown an enhancement power ~32 times with respect to the incident wave power. Using harmonic frequencies to excite the geometries, the power enhancement can achieve an intensity of ~64 times.
