Abstract
An alternative mechanism to generate terajets at terahertz frequencies is demonstrated using 3D dielectric cuboids. The focusing properties of the terajets are evaluated for several cuboids of different dimensions. Also, the backscattering enhancement is evaluated using metal particles within the terajet region, demonstrating a maximum enhancement of 11.38dB for a gold particle of diameter 0.29λ0. Finally, multifrequency operation is verified at the fundamental and first frequency harmonics at sub-THz frequencies, demonstrating a good agreement with numerical results in terms of the full-width at half maximum along the transversal x-axis (FWHMx).
