A threshold condition has been established for excitation of VLF electromagnetic radiation with a chorus structure of the dynamic spectrum in the daytime magnetosphere using the BPA (Beam Pulse Amplifier) mechanism for amplifying short noise electrom

Abstract The October effect is known as a rapid and strong decrease in the signal amplitude of radio waves with very low frequency (VLF), reflected at the lowest edge of the ionosphere. This strong decrease can be observed only during the daytime. Al

Spaceborne antennas operated in the very low frequency (VLF: 3-30kHz) ranges play important roles in ionosphere exploration, satellite communication, and submarine communication. In this paper, we idealize the receiving antenna mounted on the satelli
