This paper presents an investigation of terajets formation by dielectric periodic structure at terahertz frequencies in effective medium regime (photonic metamaterial). The dispersions of effective permittivity for three periodic structures formed by different types of plastics (ABS, PLA, Crystal) were analytically obtained for both regimes. Numerical simulation of this structure was performed by using COMSOL Multiphysics. The terajet formation was numerically shown.
