In analytical studies they permit one to determine some unknown functions while in numerical investigations they enable one to improve the convergence of some processes by introducing beforehand the edge singularities into the field functions. This work is devoted to the analysis of wedge configurations bounded by material sheets having different constitutive parameters. From mathematical point of view, the problem can be reduced to 9 canonical types. These canonical types are investigated in full detail by introducing the confluence concept which permits one to reveal also the logarithmic singularities, if any.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.

The calculation reduces to a solution of the Helmholz equations for the electric and magnetic vector potentials. The solution of the problem is obtained in an approximation of a thin antenna (in relation to the wavelength) and given distribution of electric field intensity along the slot. Expressions for the electromagnetic field intensity, radiation power, and conductivity of the longitudinal and transversal slot antennas are obtained. They are presented in a form of double series over the eigenfunctions of the perfect plane waveguide and the azimuth eigenfunctions of the cylinder. Such a representation is very convenient for numerical calculations. Using the expressions obtained the numerical calculations of real and imaginary parts of the radiation conductivity and impedance are performed. The influence of the magnetodielectric coating and geometrical parameters of the problem on antenna characteristics is analysed.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.
