Type: Grant
Filed: Feb 18, 2021
Date of Patent: Dec 14, 2021
Patent Publication Number: 20210306020
Assignee: Nokia Technologies Oy (Espoo)
Inventors: Senad Bulja (Dublin), Dirk Wiegner (Schwaikheim), Wolfgang Templ (Sersheim), Rose Kopf (Green Brook, NJ)
Primary Examiner: Junpeng Chen
Application Number: 17/178,700

Abstract:  The main idea of the present invention submission centres on the absorptive switch featuring reflective loads based on transition metal oxides (TMO). Absorptive switches operate on the principle of rather absorbing and not reflecting the unwanted signal. This is best demonstrated in Fig. 1. An exemplary realization of the switch is shown in Fig. 2.
