image: Figure 1. Schematic of imaging under real-frequency and synthesised complex frequency excitation in a superlens. The same object, when imaged through a superlens under different real-frequency ...
Figure 1Schematic of polariton propagations under real frequency and synthesized complex frequency excitation. While polariton waves at real frequencies have limited propagation distance, combining ...
Frequency response is defined as: A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it. It is a phasor whose magnitude is the ratio ...
