Expansion of logic operations through cascading. The outputs of the proposed metamaterial-based logic gates (OR, XNOR, NAND), implemented at three distinct resonance frequencies, are cascaded with a NOT gate, resulting in three additional logic functions: NOR, XOR, and AND, respectively. This demonstrates the potential scalability and functional versatility of the proposed frequency-multiplexed metamaterial design.
