Accelerating standing electromagnitic waves withing EmDrive engine cavities

Accelerating standing waves representing the sum of oppositely travelling accelerating and decelerating electromagnetic waves of same frequency are considered. Examples of accelerating standing electromagnetic waves within optical and microwave cavities are presented. It is shown that accelerating standing electromagnetic waves ideally explain EmDrive engine working principle. Trust creation by accelerating standing electromagnetic wave within cavity with dispersion is considered. Mistake in EmDrive thrust calculation made in one of the previous paper is corrected. The similarities and differences between EmDrive engine and the jet engine are displayed.
