Abstract:

For a microwave radiation within λ = 1-10 cm, a possibility was shown to construct a nonstationary multimode waveguide channel from conducting nanoparticles elongated along one direction based on the nanoparticle concentration in air (g/m³). It is shown that if the particle length 10-12-fold exceeds the transverse dimensions, then the input radiation aperture is 13°-22° that is 4-7 times higher than for spherical nanoparticles. A sharp increase of polarizability of extended nanoparticles allows decreasing their volume concentration. At the hundred-fold extension of nanoparticles the wave field intensity can reach 10⁴ V/cm, at which the mode of nanoparticles ignition is absent due to the field emission.
