Resonant Dielectric Structure as a Lens for Super-Resolution Imaging

In this article the generalized results of full width at half-maximum intensity (FWHM) of “terajets” are presented for a parallelepiped and cubic structures made of five different photopolymers in 0.05-0.35 THz frequency range. The smallest FWHM parameter was achieved for cubic structure. It was equal to 0.198λ.
