摘要:

Commercially available 3‐cm microwave equipment can produce predictable diffraction patterns if precautions are taken to eliminate standing waves resulting from reflections from various surfaces. Equipment modifications and operating procedures are described for a student laboratory experiment involving single‐slit diffraction in the transition range between Fraunhofer and Fresnel patterns. Polarization measurements are also described.
