Abstract
A method of changing phase of a microwave electromagnetic beam in free space is provided wherein a cascade of device layers is located transverse to a path of the microwave beam. Each of the device layers have one or more columns. Each column has a device combination series-coupled to an adjacent device combination in the column. Each device combination has a first device having inductive characteristics at microwave frequencies and a second device series-coupled to the first device. The second device has at microwave frequencies characteristics of a fixed capacitance in parallel with a variable capacitance. The capacitance of one or more of the second devices is variable to establish a desired phase shift and a desired frequency band edge within a desired frequency pass band.
