DESCRIPTION:Speakers: Oleg Kameshkov ()\nIn the terahertz plasmonics\, it 
 is widely used wavelength 1D grooved metal gratings for excitation of surf
 ace plasmon polaritons (SPPs). SPPs are traveling charge density waves at 
 the surface of conducting materials. Since these modes have a non-radiativ
 e nature\, it is possible to excite them only if the configuration providi
 ng the wavevector-matching condition between the incident light and SPP di
 spersion law. The wavelength gratings are the most suitable and cheaper so
 lution to satisfy this requirement.  The careful optimization of the most 
 suitable experimental parameters by the numerical simulations leads to the
  enhancement of surface plasmon resonance response. In this paper\, numeri
 cal results of grating optimization with different groove profiles are dis
 cussed. The work was supported by RSF grant 19-12-00103\n\nhttps://indico.
