A Dual-Mode Dielectric Resonator Filter With Planar Coupling Configuration Hai Hu, Student Member, IEEE,andKe-LiWu, Fellow, IEEE Abstract—This paper presents a novel dielectric resonator filter exploiting dual degenerate modes. The dielectric rod resonators are short circuited on the top and bottom surfaces to
Resonator Microwave Bandpass Filters Junyi Liu and Ke-Li Wu , Fellow, IEEE Abstract—The synthesis of coupled resonator bandpass filters has been a classic theme of research for the past half century. Continuous efforts have been paid to explore new coupling topolo-gies. Needless to say, the ultimate goal for filter synthesis is to
In the dual-mode resonator, two dissimilar TEM modes are generated by forming two perpendicular metalized blind holes in a silver-coated cuboid-shapes dielectric block.
FIG. 1. Resonator-enhanced electro-optic comb generator.(a) Schematic of a canonical electro-optic (EO) comb gener-ator comprising an EO (˜(2)) phase modulator inside a free-space Fabry-Perot (FP) resonator. A continuous-wave (CW) laser is coupled into the resonator and an optical frequency comb is generated at the output.
We generalize the distributed delayed resonator (DDR) concept by incorporating the previously unutilized but inevitable feedback loop delay, thus creating a so-called multiple-delay distributed delayed resonator (MD-DDR) for complete vibration suppression.
The effect of internal resistance of a Helmholtz resonator on acoustic energy reduction in an enclosure and the multimodal coupling-based Helmholtz resonator design are investigated. Using the analytical solution of a resonator-enclosure interaction model, an energy reduction index is defined in a frequency band to optimize the resonator ...
Resonator Filters With Cascaded Topologies Yan Zhang , Student Member, IEEE, Fabien Seyfert , Smain Amari, Member, IEEE, Martin Olivi, and Ke-Li Wu , Fellow, IEEE Abstract—This article presents a new synthesis technique for circuits that may include dispersively coupled resonators and admitting an overall cascaded topology. A decomposition

The tuning of an acoustic resonator, in terms of its Helmholtz frequency and the internal resistance, is in- vestigated for the control of a narrowband noise in an acoustic enclosure. This paper extends our previous work
