N2 - 1D grooved metal gratings are actively used in the terahertz plasmonics for excitation of surface plasmon polaritons (SPPs). SPPs are traveling charge density waves at the surface of conducting materials. Since these modes have a non-radiative nature, they can be excited only if the configuration meets the wavevector-matching condition for the incident light and SPP dispersion law. The wavelength gratings are the most suitable and cheapest solution to satisfy this requirement. Thorough optimization of the most suitable experimental parameters via numerical simulations leads to the enhancement of surface plasmon resonance response. In this paper, the numerical results of the optimization of gratings with different groove profiles are discussed.
