Emmanuel Bacry,Stéphane Gaïffase effectively, for this purpose, the charged particles (electrons or ions) need to be kept in phase with a retarding field in the amplifiers’ case or an accelerating field in the accelerators’ case over a long distance, e.g., over a distance of the order of several wavelengths. This means that the vDelectable 发表于 2025-3-28 21:11:04
The Biopolitics of Lively Data,titutional parameters are assumed to be constant scalars and frequency independent. In fact, no medium can always be a simple medium except vacuum. Most media can only be approximated as simple media under certain conditions.肌肉 发表于 2025-3-28 23:49:53

https://doi.org/10.1007/978-3-319-48366-5reen, the propagation of the wave in front of the screen is called diffraction. In fact the propagation of wave beams with finite transverse dimensions can also be treated by means of the approach for diffraction problems. Diffraction is a common phenomenon of wave propagation. The diffraction law b适宜 发表于 2025-3-29 07:45:16
