Abstract

All the wave equations, even if linear, admit of "soliton"-like solutions, called Localized Waves (beams or pulses) which propagate almost rigidly and without diffraction, with any group-velocity. In recent years we have studied the subluminal ones, and in particular the ones at test, that is, with a static envelope. We know how to produce such "Frozen Waves" with very good transverse localization, and with a complete control of the longitudinal localization: Namely, with any shape, in the (tiny) region desired, and with an intensity that from the peak can very rapidly go down of a factor one million [therefore, not affecting the surrounding regions]. Applications are expected for tumor cell desctruction, without affecting the surrounding tissues; for new types of optical or acoustic tweezers, or scalpels; for a new kind of holography, and so on.
