磁流体中电磁场的超光速局域波

Superluminal Localized Waves of Electromagnetic Field in Vacuo

Peeter Saari

摘要:

介绍了自1990年初发明以来深入研究的所谓X型波的电磁版本的概述。是超声波这些波可能在横向和纵向上都是极其局部化的,而且--这被认为是最令人吃惊的--在超光速上传播而没有明显的扩散。重点是相对论因果关系的问题,各种数学描述和实际应用的可能性的波。

英文摘要:

Presented is an overview of electromagnetic versions of the so-called X-type waves intensively studied since their invention in early 1990.-ies in ultrasonics. These waves may be extremely localized both laterally and longitudinally and - what has been considered as most startling - propagate superluminally without apparent spread. Spotlighted are the issues of the relativistic causality, variety of mathematical description and possibilities of practical applications of the waves.
