Congratulations to CMRI postdoctoral researcher James Capers on his latest paper ‘Manipulating the quasi–normal modes of radially symmetric resonators‘ which has been published in Optics Express. In this work, co-authored by CMRI PhD alumni Dr Dean Patient and assistant professor Dr Simon Horsley, James and colleagues derive methods for controlling the resonant frequency, linewidth and multipolar nature of the resonances in radially symmetric structures. Control of these values is crucial for tailoring the frequency response of a structure and represents an important step in using radial symmetric resonators for energy harvesting and sensing.
Discussing his latest work, James shares the following thoughts:
I’m very happy to share my newest paper with Dean Patient and Simon Horsley, in which we develop some simple techniques for manipulating the complex eigen-frequencies of radially symmetric resonators. The two approaches we present allow for the control of frequency, linewidth and multipolar nature of the resonances simultaneously. We expect our work to be useful in a wide range of contexts, from metamaterial design to sensing and optical computing. It was great fun to collaborate with Dean Patient on this!Special thanks to Joshua Glasbey and Dr. Ian Hooper for their comments, questions and feedback along the way.
