HIGH SELECTIVITY SINGLE WIDEBAND AND QUAD-BAND HTS FILTERS USING NOVEL QUAD-MODE RESONATORS WITH SELF-COUPLED STRUCTURE

High Selectivity Single Wideband and Quad-Band HTS Filters Using Novel Quad-Mode Resonators With Self-Coupled Structure

This paper presents improved quad-mode resonators based on the open/short-end load of the center stub, which introduces the self-coupled structure.Compared with the traditional stub-loaded stepped impedance resonator (SLSIR), the proposed quad-mode resonators can significantly reduce the circuit size and further increase the design freedom.First of

Systematics of boundary actions in gauge theory and gravity

Abstract We undertake a general study of the boundary (or edge) modes that arise in gauge and gravitational theories defined on a space with boundary, either asymptotic or at finite distance, focusing on efficient techniques for computing the corresponding boundary action.Such actions capture all the dynamics Massagers of the system that are implie
