Abstract
A radome includes a liquid crystal layer, and control electrode layers and a power source for applying an electric field to the liquid crystal layer. The permittivity of the liquid crystal layer changes when an electric field is applied from the power source through the control electrode layers. Thickness and relative permittivity are selected to permit radio waves having the working frequency of a radar antenna to pass through during application of the electric field.
