Intermediate hypersurface檢視原始碼討論檢視歷史

Self made metal super surface devices for attack; Then, the device is placed between the transceiver devices in the legal command transmission path, and the phase mutation of the signal is induced by the metal resonance ring array on the metal super surface to produce controllable directional diffraction radiation. The hidden diffraction eavesdropping link is successfully established, and the theft of communication information is realized.
