| Abstract: | A new method is proposed to enhance microwave radiation with a wavelength of λ ∼ 1 cm in an active medium comprising elongated conducting nanotubes dispersed in air, which is energy pumped by a nonstationary electric field. For a volume fraction of nanoparticles c 0 ≈ 10−3 in air at atmospheric pressure, the necessary value of the nonstationary pumping electric field (generated by a high-power nanosecond pulsed voltage source) is estimated at ∼ 200 J/m3 and the weak signal gain is estimated at Γ0 = 0.055 m−1. One possible mechanism of microwave radiation enhancement in a spatial resonator is considered. |
