Understanding the mechanism of nonlinearity in SAW/BAW devices is growing up in importance because these, even being weak, can cause desensitization of the receivers and limiting their performance. Proper nonlinear distributed ...

A uniplanar filter based on two coplanar-waveguide odd-mode resonators is presented. The resonator feeding point is easily reconfigured using PIN diodes. As a result, the filter features reconfigurable bandwidth. A multimodal ...

In the wave energy sector, an increasing concern regarding the grid connection of wave energy converters is recently being experienced, as well as in the main challenges resulting from the grid integration of large scale ...

This paper presents a novel approach for tuning substrate integrated waveguide resonators, realized by placing an additional metallized via-hole on the waveguide cavity. The approach presented here can be applied as a ...

Continuous–time filters (CTFs) with automatic tuning loops are nonlinear feedback systems with potential instability. Thus, their appropriate linear dynamic modeling should be obtained to assure stability in case of an ...

This paper present a three-phase four wire hybrid filter able to perform a selective cancellation of harmonic currents based on resonant controllers. As it will be shown in this work, this kind of control permits to ...

The control of active and reactive power for the Renewable Energy Sources (RES) based power plants are very important. The injection of active and reactive power to the grid is normally controlled at the Point of Common ...
