Abstract
The technology described herein is directed towards a design and implementation of a unit cell for a reconfigurable intelligent surface/reflectarray by incorporating reconfigurability within a phase-delay element of the unit cell. Reconfigurability is directly incorporated into the unit cell via a variable length phase delay line element and PCM-based (e.g., mmWave) phase shifter that determines the unit cell's phase shift by changing the length of the phase delay line element. One implementation is directed to a monolithic integration of the element using chalcogenide materials as switch elements with pulsed actuation to switch among different available lengths that determine the length of the phase delay line element, resulting in a significant reduction in power consumption, area saving, and digital reconfigurability.
