We prove that N(f)=|L(f)| for any continuous map f of a given infranilmanifold with Abelian holonomy group of odd order. This theorem is the analogue of a theorem of Anosov for continuous maps on nilmanifolds. We will also show that although their fu

The development of advanced additive manufacturing (AM) and material processing techniques is currently a topic of great interest to broad communities of scientists and engineers. In particular, there is a need for AM processes capable of producing f

The generation of low-frequency radiation from a short pulse (∼100 fs) laser with mJ energy incident on a metal surface is investigated. The electrons within the metal surface absorb energy from the laser pulse, increasing in temperature to a few e

Transparent magnesium aluminate spinel (MgAl2O4) ceramic has excellent transmission from the UV to mid-wave IR. It is rugged with strength that is 5x that of glass. Spinel also has better IR transmission compared to sapphire and ALON. Because of its

Ongoing NRL experiments have revealed long-lived $( \sim 20$ microseconds), efficient microwave reflection from a laser generated plasma region in air. This phenomenon is distinct from the short-lived response $( \sim 10$ ns) typical for laser produc

The generation of low-frequency radiation from sub-picosecond laser pulses incident on metal targets is investigated. The laser field drives time-varying currents in a thin sub-surface layer of the metal, which emits broadband radiation that peaks at

We report experimental results on a two frequency gyrotron, operating in the ${\rm TE}_{22,6}$ mode at 110 GHz and the ${\rm TE}_{24,7}$ mode at 124.5 GHz. The gyrotron uses the same electron gun as a previous single frequency 110-GHz gyrotron, with

A simple method is presented for the analysis and design of gyrotron output couplers based on a Vlasov-type launcher and a single focusing mirror. It is shown that a quasi-analytical solution to the Kirchhoff diffraction integral can be implemented t
