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.

WebNov 20, 2015 · Many-body properties of a quantum system show drastic changes according to the geometry of an underlying lattice structure. One of the textbook examples is an antiferromagnet on a frustrated lattice geometry (), where the geometric frustration prevents spins from Néel ordering and the system exhibits more nontrivial, correlated ground … WebSep 23, 2015 · A fully coherent dual band radar system based on a single photonic-assisted transceiver is presented. Photonic technologies have been used for simultaneous generation and detection of radar signals in the S- and X-band. The sharing of a single transceiver for both the frequency bands allows for a perfect coherence among the … WebThe optical polarization is a genuine non-equilibrium quantity that decays to zero when the excited system relaxes to its equilibrium state after the electromagnetic pulse is switched off. Due to this decay which is called dephasing, coherent effects are observable only for a certain temporal duration after pulsed photoexcitation. Various ... marine and coastal process
