So passive RFID systems that rely on near-field communication (typically low- and high-frequency systems) have a shorter read range than those that use far field communication (UHF and microwave ...

NFC, or near field communication, is a popular wireless technology that allows you to transfer data between two devices that are in close proximity to each other. It’s often used as a faster and ...

RFID reader antennas emit electromagnetic radiation (radio waves). If an RFID tag is outside of one full wavelength of the reader, it is said to be in the “far field.” If it is within one full ...

In the early stage of near-field microscopy, apertured tips were used to confine the light by passing it through a tiny hole at the apex of the tip. Although this kind of NSOM has certain ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...
