WebCoherent detection originates from radio communications, where a local carrier mixes with the received radio frequency (RF) signal to generate a product term. As a result, the … WebFeb 6, 2024 · Abstract We demonstrate theoretically the existence of optical coherence band gaps by performing simulations of partially coherent light incident on a linear array of circular holes in a subwavelength-thickness gold sheet. We use a simple scalar Foldy-Lax system of equations for our model.
