6 Electromagnetic Phenomena in Metals with Constant Permeability

6.1 Application of Multiple Reflections of Electromagnetic Wave

In Section 4.3, we presented fundamentals of calculation of electromagnetic field inside metal walls using the method of multiple reflections of the wave inside metal sheets. Using that method, in Section 4.4 the active and reactive power consumed in these walls and electromagnetic screens were calculated. In Section 4.9.1, the coefficients of power loss in cylindrical screen were developed, and in Section 5.5.1— impedances of rotor bars of a deep-slot induction motor. Other applications of this method will be given in the next sections.
