In nanotechnology, the ability to control and manipulate waves at the nanoscale is essential for a variety of applications, including nanophotonics, quantum computing, and nanofabrication. Gaussian waves are especially useful in scenarios where localization and minimal diffraction are required, such as in optical tweezers or precision measurement techniques. Plane waves are fundamental in describing delocalized wave functions, which are crucial for understanding the behavior of electrons in nanostructures.
