Considered problem is the reading of multiple RFID tags in the region of space, which is bounded by metal walls and has resonant radio-engineering properties. Obtained results show that it is possible to get reliable automated monitoring of items with tags by forming of a local electromagnetic field (EMF) with the help of slow-wave structures (SWS).

Traditional RF applications required power transistors that could withstand high mismatch conditions, but the ability of the latest generation of devices to handle even more severe mismatches has enabled new and emerging high-power RF applications, as well as dramatically improving reliability and simplifying more mature applications.

This paper discusses the setup details for the demo shown in this video Head to Head: NI 5665 vs. Traditional Boxed Instruments. The demo compares the performance and speed of the NI PXIe-5665 with the Agilent PXA. Rather than comparing the datasheet specifications of both instruments, this video compares the two instruments while performing real- world test scenarios.

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.
