We present a full-wave numerical tool for the simulation of plasma antennas. The tool makes use of a hybrid formulation that allows treating the plasma with a Finite Element discretization, and the metallic parts with the Method of Moments. The finite element discretization is solved using a state-of-the-art sparse solver (MUMPS) in order to reduce the computational time at a minimum. The accuracy...
We present the numerical analysis of a reconfigurable plasma antenna array (PAA) comprised of a metallic half-wavelength dipole and a variable number of cylindrical plasma tubes that are arranged in a planar rectangular lattice. Our simulations, carried out with the linear embedding via Green's operators (LEGO) method, indicate that beam-forming and beam-steering can be realized and controlled by...
Neutrons are unique to diagnose materials and excite nuclear reactions with a large field of applications. For the first time a new ion acceleration mechanism (BOA) has been used to generate intense, directed neutron beams.
