Incoherent emission

WebThe incoherent emission from an undulating electron beam in the presence of metallic boundaries is analyzed. A general method of solving Maxwell's equations is used to express the field of a single particle in terms of vector waveguide modes. It is shown that the radiation characteristics depend upon a parameter involving the energy wiggler ... WebDec 10, 2024 · We investigate the effect of local incoherent emission, γ ↓, adding it to both ensembles, showing that the excitation exchange becomes only transient, as the excitation lost by the second ensemble (red thick dashed curve) is partly acquired by the first ensemble (black thin dashed curve) at short times; eventually also the second ensemble ...

WebApr 4, 2024 · Jitter radiation is incoherent emission in general (Medvedev 2000). However, in this paper, we suggest that the jitter radiation in our model is coherent. We provide two reasons. First, kinetic turbulence provides a perturbation field to jitter radiation in our scenario, and the jitter radiation can have emission in a small coherent length scale.

WebApr 24, 2024 · The challenge of incoherent emitters has been addressed by using many equally (Lee et al. 2003; Kim et al. 2014) or randomly (Lee et al. 2005) distributed dipoles with random initial phases or by multiple runs with single dipoles at different positions which are incoherently superimposed afterwards (Callens et al. 2014 ). WebThe incoherent emission from different points on the wave function (resulting from the delta-function term in Eq. 3) is a manifestation of quantum decoherence of the emitted light, … WebJul 22, 2011 · We study dynamics of a two-level superconducting quantum system, analogous to a natural atom in an open space, by measuring the evolution of its coherent and incoherent emission.
