Abstract

A method for inertial confinement fusion driven by powerful long wavelength electromagnetic pulses (EMPs), such as ${\rm CO}_{2}$ laser pulses or high power microwave pulses, is proposed. Due to the high efficiency of generating such long wavelength electromagnetic pulses, this method is especially important for the future fusion electricity power Special fuel targets are designed to overcome the shortcomings of the long wavelength electromagnetic pulses.
