PIM is a form of intermodulation distortion that occurs in components normally thought of as linear, such as cables, connectors, and antennas. However, when subject to the high RF powers found in cellular systems, these devices can generate spurious signals. An on site PIM test is a comprehensive measure of linearity and construction quality
We have used FEM technique of COMSOL to calculate the transmission through several MDSs. We have also produced plots of channeled power through the MDS. We have calculated the cross sectional power at the image plane to determine the super-resolving capability of various MDSs.
