Abstract
Transformation electromagnetics, which provides a new way to manipulate electromagnetic waves with coordinate transformation methodology, has become an important inspiration in wave propagation theories. In this paper, a two-dimensional cylindrical electromagnetic wave expander is discussed with its two basic variables. The variations of each constitutive parameter extremum are analyzed in detail with these two variables respectively. The different curves that vary with the basic variables can provide some guidance for the production of wave expanders. The scattering minifying functions of the wave expander are further studied through numerical simulations of two-dimensional embedded aircraft models and the quantitative calculations of their scattering width values, along with which the scattering width of the expander itself is also studied. A conclusion is drawn that the minification degree of the scattering cross-section of the embedded object inside the wave expander depends on the reduction factor of the wave expander.
