A development from scientists at Shanghai Jiao Tong University in China aims to redefine underwater surveillance by using ...

“The principle involves utilizing ultra-wideband, radially polarized, conical coaxial horn antennas to create a rotating electromagnetic wave structure,” the scientists said in a press statement.

"The principle involves utilizing ultra-wideband, radially polarized, conical coaxial horn antennas to create a rotating electromagnetic wave structure," the team explained in a statement.

Bandwidth spans 1.3GHz to at least 10GHz. “The principle involves utilising ultra-wideband, radially polarised, conical coaxial horn antennas to create a rotating electromagnetic wave structure,” ...

The conical coaxial horn antenna generates an electromagnetic field in free space that rotates around the propagation direction of the wave structure. The researchers experimentally mapped the ...
