The paper considers the electric field line distribution in the cross-section of a rectangular waveguide containing an inhomogeneous insert with inherent anisotropy of its electric and magnetic properties. The finite difference method has been employed for the Maxwell equation discretization for a random anisotropic medium bounded by the waveguide or resonator walls. A set of linear algebraic equations for the electric field components in the inhomogeneous anisotropic medium has been obtained and solved using the conjugate gradient technique. The research is illustrated by some computations on the electric field lines in the cross-section of the anisotropic insert in the rectangular waveguide.
