| Popis: | The interaction of monochromatic electromagnetic radiation with a photoionized plasma formed during multiphoton ionization of inert gas atoms is studied. It is shown how electron collisions with neutral atoms affect the surface impedance and absorption coefficient. The possibility of a significant absorption coefficient growth in the regimes of high-frequency and normal skin effects due to the manifestation of the Ramsauer-Townsend effect was revealed. The conditions under which the interaction of test low-frequency radiation with a photoionized inert gas plasma is similar to the interaction with a dielectric with a permittivity having a small imaginary part are established. |
