WebAug 18, 2024 · Coherent CL has two sources of radiation: transition radiation and surface plasmon polaritons. Unlike in incoherent CL, the emitted photon has a fixed phase relation with incoming electron. In addition, the emitted light is always polarised. Coherent CL is always present but can be obscured by incoherent CL as it is a low probability event. Webthe coherent interference between light waves in the structure. We show how partially coherent and incoherent layers may be incorporated into the calculation by means of an appropriate integration. The work is an extension of previously published work regarding a particle (photon) model for absorption in such structures. mickey walker obituary
