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 similar to 32 times with respect to the incident wave power. Using harmonic frequencies to excite the geometries, the power enhancement can achieve an intensity of similar to 64 times.
