Abstract
A phase shifter comprising an actuator coupled to a dielectric. When the dielectric is inserted into the waveguide in response to actuation by the actuator, the phase velocity of the incoming electromagnetic wave is decreased, resulting in a phase shift of the electromagnetic wave. A desired phase shift and a low insertion loss can be controlled by positioning of the dielectric and engineering the permittivity of the dielectric.
