With the increasing importance of space-borne antennas in very low-frequency (VLF: 3–30 kHz) transmitting system, it is essential to study radiation characteristics of a radiator in ionosphere. In ...

The quasi-isotropic conductor stacked by the second generation (2G) high temperature superconducting (HTS) tapes is a promising choice for current transmission with low AC losses. In this paper, AC ...
