Teaching university courses, which deal with the phenomena of the electromagnetic (EM) substantiality and their applications, is rather difficult due to their abstract nature. Therefore, teaching has to be accompanied by clear explanations and by simulations illustrating the exa- mined topics. This is why an electronic textbook (ET) of EM waves and applications was developed. The ET presents theoretical descriptions

The dispersion characteristics for magnetostatic surface waves in a left handed (LHM)/ferrite/ metal-strip-grating structure have been investigated. We found that, the waveguide supports backward TE waves since both permittivity and magnetic permeability of LHM are negative. We also illustrated the dependence of wave frequency on the reduced wave number for a grating shielding parameter, g values restricted by the range 1 0 ≥ ≤ g. It is shown that the grating shielding parameter, g induces magnetostatic backward shorter waves. The leakage through the grating increases with the wave number. The shorter backward magnetostatic waves are guided by the thicker waveguide where the best confinement is achieved .
