N2 - Currently, in photonic integrated circuits, the circuit size is limited by diffraction, which acts as a barrier to further development in the field of optical communications. Plasmonics could potentially address this size mismatch between electronic and photonic components. Photonics and plasmonics can complement each other, given the appropriate conditions, allowing optical signals to be converted into surface plasmon-polaritons (SPPs) and vice versa. Therefore, plasmonic integrated planar circuits for wireless communication devices are actively being developed. Transitioning to the terahertz (THz) frequency range will enhance data transmission and processing speed. In the development of plasmonic integrated circuits, understanding the optical properties of surfaces is crucial. Current methods for determining the optical properties of surfaces in the THz frequency range lack sufficient sensitivity to transitional surface layers of metal and films that are much thinner than the optical wavelength. This work will demonstrate experimental methods for measuring the penetration depth of the SPP field into the air. Through these methods, and utilizing other plasmonic refractometric characteristics, it is possible to reconstruct the effective surface dielectric permittivity of the metal.
