Abstract: Solar concentrators with multiple stages are typically favored to reduce the overall dimension of the concentrated photovoltaics (CPV) design. However, dual-stage concentrators like ...
Abstract: In this article, we propose a low reflection folded waveguide (LRFWG) as the slow wave structure (SWS) for the development of a terahertz (THz) traveling-wave tube (TWT). Our simulation ...
