The method longitudinal sections for the calculation the own waves of shielded waveguides with a complex form of cross-section

The method which can be used for calculation of own waves shielded waveguides with any law of change of parameters of a waveguide from cross-section co-ordinate is offered. The homogeneous system of linear algebraic equations to which the decision of a considered problem is reduced is received. Method approbation on an example partially filled shielded waveguides is spent.
