SPECIAL FEATURES OF ELECTROMAGNETIC WAVE PROPAGATION IN A TWO-LAYERED CYLINDRICAL WAVEGUIDE WITH RIGHT- AND LEFT-HANDED MEDIA. PART 2

Results of computer modeling of the coefficients of waveguide mode propagation in a two-layered circular screened waveguide are presented. The waveguide center is filled with the medium having a negative refractive index. The results presented here suggest that frequency transparency windows, complex waves, waves with anomalous dispersion, and waves with significant slowdown of the phase velocity exist in such waveguides.

System of automated measurement of electromagnetic response of anisotropic materials in quasi-optical beams

Description of automated measuring system of electromagnetic response of anisotropic materials in quasi-optical beams was presented. Angular dependence of transmission coefficient for anisotropic materials based on microwires periodic structure in the UHF range was shown.
