Applicant: Alcatel Lucent (Paris)
Inventors: Senad Bulja (Dublin), Rose F. Kopf (Green Brook, NJ)
Application Number: 16/018,212

In this invention a Reflective-type Phase Shifter based on Electro-Chromic materials is proposed, Fig. 1. By the application of a dc bias voltage, the dielectric characteristics of the reflective loads change, resulting in an observed phase shift at the output of the device.
