Spaceborne deployable mesh reflectors are lightweight antennas made by a tensioned net supporting an RF reflecting mesh, which are deployed in orbit. The tensioned net is typically made by regular...

We present a method that enables full-wave analysis of electrically large antennas and platforms, e.g., a detailed telecommunication satellite at Ka-band. Owing to the efficient formulation, even...
