RT Journal Article ID 59071e0c210cb79e A1 Pazynin, V. L. A1 Sirenko, K. Yu. T1 The Strong Approach to Analysis of Transients in the Axially Symmetrical Waveguide Units JF Telecommunications and Radio Engineering JO TRE YR 2006 FD 2006-05-01 VO 65 IS 1-5 SP 1 OP 18 AB The exact “absorbing” conditions for virtual boundaries in the cross-sections of regular circular and coaxial circular waveguides are constructed, which allow one to truncate efficiently the computational domain of finite-difference methods as applied to the simulation of transients in open axially-symmetric waveguide resonators. The “open” initial-boundary value problems, describing the impulse TE0N- and TM0N-waves in the structure of this kind, are reduced to the equivalent “closed” ones. The so-obtained conditions are embodied in the computer programs for the analysis and model synthesis of functional units of impulse-wave radiators.
