RT Journal Article ID 7a9fdd5b0c487e17 A1 Skrynnik, Boris Kuz'mich T1 Mode Evolution in an Open Resonator with a Diffraction Grating JF Telecommunications and Radio Engineering JO TRE YR 1999 FD 1999-03-01 VO 53 IS 3 SP 70 OP 74 AB The field distribution in the open resonator of a diffraction radiation generator (orothron) has been studied as a function of the separation between the plane reflector and the reflective diffraction grating that partially covers the reflector. It has been shown that any field distribution in such a cavity can be represented as a sum of several modes of the respective cavity without the grating. Besides, each of such "clustered" oscillations behaves as a single entity. PB Begell House LK https://www.dl.begellhouse.com/journals/0632a9d54950b268,08c8c1232f8c1472,7a9fdd5b0c487e17.html
