DOI: 10.1063/5.0046369
Abstract: An ordinary high frequency radio wave radiated at the Spitze angle after reflection from the ionosphere does not return to the ground. It is converted into the Z-mode, and in the vicinity of the critical… read more here.

DOI: 10.1109/tmtt.2019.2952115
Abstract: We describe a method for the broadband measurement of the even- and odd-mode propagation constants of symmetrical coupled transmission lines. The main advantage of the method, its simplicity, lies in the lack of need for… read more here.

DOI: 10.5194/angeo-36-243-2018
Abstract: Abstract. The response of ionospheric plasma to pumping by powerful HF (high frequency) electromagnetic waves transmitted from the ground into the ionosphere is the strongest in the direction of geomagnetic zenith. We present experimental results… read more here.
