Violation of Malus Law in the Microwave Range
Malus law on polarization of electromagnetic waves is valid for microwave range with λ = 3,2 cm, if the source and receiver of radio waves use rectangular waveguides with a pyramidal horn antennas. If the microwave generator is loaded with cylindrical waveguide with finite-mechanical antenna, then there are significant deviations from the law of Malus. The reason for breaking the law is revealed.
