Diffraction and polarization of microwaves
Principle: The equivalence between visible light and microwaves as special cases of the total spectrum of electromagnetic waves can be demonstrated using diffraction and polarization of microwaves as an example. The focusing of microwaves through a plane convex convergent lens is observed and the focal distance of the lens is determined. After that, polarizability of microwaves is demonstrated by means of a metallic grating.
Tasks:
1. Measuring the irradiance of the microwave field behind a converging lens
- along the optical axis
- transversally to the optical axis.
Determination of the focal length of a synthetic resin converging lens and comparison of the results with the distribution of irradiance when no lens is used.
2. Measurement of the irradiance transmitted through a metal grating as a function of the angle between the direction of polarization and the grating bars.
