This paper introduces a new Direct Power Injection (DPI) set-up used to characterize the conducted immunity of integrated circuits (IC) with differential inputs. It allows injecting common-mode, differential-mode signals or any combination of both. For a given kind of injection, it is necessary to calculate power and phase-shift at generators. To do so, an analytic model is developed based on S-parameters...
The characterization of materials by rectangular waveguide method usually requires a sample holder and a complicated procedure of preparing specimen in order to limit the air gaps between the specimen and the boundaries of the waveguide that will affect the accuracy of measurement. In this paper, we present a technique of complex permittivity measurement with a simple MUT (Material Under Test) preparation...
Interest in wireless power transmission (WPT) systems has increased remarkably in recent years thanks to their unlimited applications in wireless sensor networks, energy harvesting systems, RFIDs and so on. The key element on the receiving side of a WPT system is the rectenna (rectifier + antenna) which receives electromagnetic power and converts it into electric power. This paper investigates space...
