METHOD FOR DETERMINING CHARACTERISTICS OF SURFACE ELECTROMAGNETIC WAVES IN FINITE-LENGTH PLASMA FORMATIONS Russian patent published in 2021 - IPC H01Q1/36 H05H1/00 H01Q5/314 H05H1/46 

FIELD: radio engineering.

SUBSTANCE: claimed method relates to radio engineering with the exploitation of plasma features in condensed media and can be used for the design of radio engineering devices, including transmitting and receiving plasma antennas (PA). The claimed method for determining the characteristics of a surface electromagnetic wave includes the selection of an additional column of ionized gas, measuring the DC voltage values for two columns of ionized gas, determining the value of the near-electrode potential drop, determining the value of the electric field strength, measuring the pressure in the ionized gas, determining the electron concentration, determining the permittivity of the plasma, determining the value of the skin layer, determining the resistance of the unit length, determining the wave resistance of the DPO, determining the wave number and wavelength for SEW, determining the frequency-dependent impedance, current strength, voltage allocated per unit length of power, efficiency coefficient.

EFFECT: increased accuracy of determining the characteristics of surface electromagnetic waves when designing PA.
