Fiber-Optic Measurement Systems: Microwave and Radio Frequency Heating Applications

EOAF 12004160 65 66 67 68 69 70 71 Abstract Fiber-optic sensors do not interfere with electromagnetic fields and are commonly used to measure temperature and pressure used in microwave and frequency heating research and applications. This article introduces the physical principles for three different types of commonly used fiber-optic sensors and discusses important parameters to be considered ...

RF-DNA: Radio-Frequency Certificates of Authenticity

A certificate of authenticity (COA) is an inexpensive physical object that has a random and unique multidimensional structure S which is hard to near-exactly replicate. An inexpensive device should be able to scan object’s physical “fingerprint,” i.e., obtain a set of features in the form of a multidimensional signal x that pseudo-uniquely represents S. For a given “fingerprint” x and without a...

Control Interfaces for RF and Microwave Frequency Synthesizers

Frequency synthesizers come in a variety of forms ranging from tiny PLL chips and moderate-size modules to bench-top signal generators [1-5]. Single-chip synthesizers are available in a die form or as surface-mount integrated circuits. They include key elements (such as RF and reference dividers, phase detector, lock indicator, etc.) required to build a simple single-loop PLL synthesizer. More ...
