Abstract
The microwave impedance across an aperture in a conductive shield member of a transmission structure is varied as a microwave signal transits the aperture. The impedance is changed by positioning a variable impedance device across the aperture. A slit divides the shield member into two portions to facilitate the application of a modulating signal (56) across the device.
