Measurement of polarization rotation of electromagnetic waves in industrial environments

In a harsh environment with dense metallic equipments, research on wireless channel is helpful to improve the performance of industrial wireless sensor networks. Simulation of polarization rotation of electromagnetic waves is performed, which is also verified by a test platform designed by ourselves. The results suggest that, the polarization rotation of electromagnetic waves induces random signal fading, meanwhile, decreases the cross polarization discrimination. Well designed polarization diversity schemes should be applied to fight the random fading and thereby enhance the robustness of the wireless sensor networks.
