Cylindrical vector beams have a great number of applications, including electron acceleration, material proces-sing, high-resolution metrology, microellipsometry and spectro-scopy. Methods and approaches for forming beams with complex polarization structure are practically absent in the terahertz range. Using Body of Revolution Finite Difference in Time Domain (BOR FDTD) method the reflection and transmission coefficients of the waveguide modes with different symmetry and polarization are obtained numerically for the diffraction mirror in the form of the azimuthal periodic multi-ring small-scale and large-scale diaphragms positioned within a circular hollow dielectric waveguide. Obtained results can find their application in development of new intracavity methods of forming of the radiation with spatially inhomogeneous polarization in terahertz range lasers. |
