Abstract :
We implemented a multi-mode approach for performance optimization of a near-field array, which resulted in negligible total reflected power and nearly optimal transmit performance for the modes selected. The total reflected power obtained for all given excitation modes is proposed as a circuit-level figure-of-merit for transmit performance estimation.
