RT Journal Article ID 10b91cad741f4747 A1 Svishchov, Yu. V. T1 ON QUALITY OF MAGNETIC TE0nq EIGENMODES OF AN OPEN RESONATOR WITH SPHERICAL MIRRORS JF Radio Physics and Radio Astronomy JO RPRA YR 2010 FD 2010-11-10 VO 1 IS 4 SP 335 OP 341 K1 open resonator K1 magnetic eigenmodes K1 Q-factor K1 mode coupling K1 mode degeneracy points AB Numerical simulation results are presented on the characteristics of axially-symmetric magnetic eigenmodes of a spherical-mirror open resonator (OR). Effect of the resonance fall/rise of the diffraction Q-factor by one to two orders of magnitude as OR geometrical parameters change has been revealed and studied. The existence of eigenmode degeneracy points in the complex plane has been proved. PB Begell House LK https://www.dl.begellhouse.com/journals/6fd1549c0e2c05da,15826c680ad7d10a,10b91cad741f4747.html
