Abstract

The solution of the wave diffraction problem that is obtained in [1] is modified and applied for modelling of the axially symmetric transverse magnetic (TM) waves scattering from the conical probe in the presence of half-spherical defect on the plane surface. This structure is modelled by a bicone with semi-infinite and truncated semi-infinite perfectly conducting conical shoulders and the spherical diaph­ragm. The structure is excited by the radial electric dipole. The mode-matching and analytical regularization techniques are used for the solution of the problem. Based on the obtained solution, the near and the far fields scattered from the defect are analysed for determining the information parameters for its identification.
