• ] (Figure 1a). The basic element of the receiving matrix is a dipole bow-tie antenna, in the gap of which the CEB is embedded (Figure 1b). This matrix is located on a silicon substrate, which is 260 µm thick. Since the operation of the CEB in the matrix is assumed to be in the voltage bias mode, the
