Cylindrical wave spectrum
WebMar 30, 2016 · The boundary value problem of the propagation of an electromagnetic field along a cylindrical conductor in an isotropic plasma medium has been solved by the impedance method. The boundedness of the wave spectrum of such a guiding structure has been shown. WebOn a certain direction where electromagnetic wave fields are projected (or considering a situation where two waves have the same polarization), two waves of equal (projected) amplitudewhich are in phase (same phase) give the amplitude of the resultant wave sum as double the individual wave amplitudes, while two waves of equal amplitude which are …
