Collection of ENEA technology and expertise
High intensity electromagnetic fields with fast transients and on big volumes.
Innovative method for the rapid generation of electromagnetic fields (EMFs), based on the the extraction of electrons due to laser-matter interaction (LMI). The LMI becomes source of charge for the creation of EMFs quasi-static or RF-microwaves on big volumes, by means of structures similar to capacitors. The produced EMFs can be stationary with fast rise-times, sinusoidal at high intensity or traveling waves, with tunable time and space distributions, employable in a wide range of applications.
Application sectors
Problem to solve
Innovative method for the generation of high-intensity electromagnetic fields, based on the process of the electrons extraction from the material due to laser-matter interaction. Such a phenomenon leaves on the material a high residual electric charge in very short times, comparable with the time duration of the laser pulse used. This method resolves the classical problems of generation, without the use of cumbersome high power generator, of: 1) fast and intense EMFs due to rapid charge;discharge of capacitors; 2) high-charge short pulses propagating on a transmission line. It also allows for the absoulute syncronization of the generated fields with the driving laser pulse.
