"manipulates electromagnetic waves... no digital-to-analog conversion... overcomes low data transmission rates/ poor information mapping efficiencies, using 1-bit encoding sequences with length on odd prime, producing constellation diagram at direction of 1st harmonic, exhibiting distinctiveness/ symmetry achieving highest information mapping efficiency... printed circuit board of 3 metallic/ 2 substrate layers... phase shifter module controls each column's phase state... modulation is achieved directly without additional modules"
