Questions the theoretical feasibility of EM Drive based on fundamental physics

Abstract

The concept of EM Drive has attracted much attention and groups of work have been conducted to prove or verify it, of which the published experimental outcome is criticized in great details while the theoretical foundation has not been discussed. The present essay investigates on the theoretical derivations of the net thrust in the EM drive and reveals the self-contradiction arising at the very start, when the law of conservation of momentum was utilized and opposed simultaneously.
