Excitation of Electromagnetic Waves in a Plane Waveguide with Anisotropic Upper Wall

We solve the problem of propagation of electromagnetic ULF waves in a plane waveguide with anisotropic upper wall from an arbitrary source with allowance for an arbitrary inclination of the magnetic field. The procedure for calculating magnetic components of the signal radiated by horizontal and vertical dipoles is developed in detail. The solution is presented in the form of the Fourier–Bessel transform of the desired field components. Impedance-type boundary conditions were used for an arbitrary inclination of the magnetic field. The obtained solutions can be used for interpreting experiments on measuring the spectra of ULF electromagnetic noise in various geographical regions and calculating parameters of ULF signals from controlled sources.
