Design of passive ring resonators to be used for sensing applications [PDF]

Journal of the European Optical Society-Rapid Publications, 2009
In this paper we report on the effects of two optical beams counterpropagating in a passive ring resonator that is the building block of several devices in a lot of sensing applications. By using the transfer matrix method in combination with the coupled

A Novel Dual-Mode Dual-Band Bandpass Filter Based on a Single Ring Resonator [PDF]

Journal of Electromagnetic Engineering and Science, 2020
In this paper, a dual-mode bandpass filter that operates in two different bands is proposed. A circular patch with a small circular hole is set as the basic resonator, and, as the circular hole moves, the linewidth of the ring resonator becomes non ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
