Abstract :
The operating principle and application of the Mach-Zehnder interferometer and its use as a nonintrusive electric-field measuring device are discussed. The methods and technical difficulties in the construction of these sensors are explained, and some of the results are presented. The device uses a microantenna that allows collection of charges close to the waveguide. As a result, the device is sensitive to a small variation in external electric fields. In principle, the length of this antenna can be adjusted for a specific radiation measurement.<>
