“…We will choose the time dependence in the form of exp(−jωt) and consider the case of H-polarization, where the field has non-zero components H x , E y , and E z . Let us represent the H x component of the magnetic field in the following form [18,19]:…”

“…Infinite systems (9), (17), and (18) of linear algebraic equations were solved by the reduction method [18,19], and the solution accuracy was controlled numerically. Comparison of the obtained solution for the case of incidence of the zerothorder beam having the width w 0 ≥ 2λ on the open end of the waveguide having the width d < λ/4 with the solution of the mathematically rigorously defined problem of incidence of a plane wave on the open end of the waveguide of the same width with an infinite flange [21] yields that the difference between the values of the coefficient c 0 amounts to several percent and decreases with increasing w 0 /λ and decreasing d/λ.…”

621.372 We study theoretically and experimentally the efficiency of excitation of an open resonator by a waveguide. A two-dimensional model of a quasioptical two-mirror open resonator, which is excited through a coupling element in the form of an open end of a plane-parallel waveguide, is proposed. The field of the open resonator is represented as the superposition of Gaussian wave beams and its scattering on the coupling element is described by solving the problem of diffraction of waveguide waves and Gaussian wave beams on an open end of a flanged waveguide. Properties of the mirrors and the resonator loss are specified from physical considerations. The calculation results are compared with the experimental data, and a physical interpretation of the obtained results is offered. The factors which influence the efficiency of excitation of an open resonator are identified.

“…Verification of a method by the calculation of reflection coefficient of a quasioptical OR Reliability of obtained results is obtained by the comparison of the characteristics of the partial modes of hybrid oscillation calculated after [7] with the same characteristics found according to the proposed algorithm. The dependence of the reflection coefficient F obtained according to [4,7] for a two-dimensional OR at the excitation by the plane waveguide, of a Gauss TEM,,9 mode and an Hermite-Gauss TEM4 8 mode, closely located to it, is given in Fig. 2 by the dots.…”

“…The displacements of maxima of the "resonant curve" of A is caused partly by the inserted to OR reactivity X, = w,L,, of the coupling device. Quasioptical model [4,7] enables one to determine the unloaded qualityfactor of OR at the excitation of the TEM09 mode and in the absence of the TEM4 8 mode, and vise-versa. The calculated by this method values of Q-factors are Q, 9 = 5692 and Q48 = 2627, respectively.…”
