Optical-approximation analysis of sidewall-spacing effects on the force between two squares with parallel sidewalls [PDF]
, 2007 Using the ray-optics approximation, we analyze the Casimir force in a two dimensional domain formed by two metallic blocks adjacent to parallel metallic sidewalls, which are separated from the blocks by a finite distance h.

Optical transmission theory for metal-insulator-metal periodic nanostructures
Nanophotonics, 2016 A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layers with periodic one-dimensional ...

Low-Power All-Optical Switch Based on Time-Reversed Microring Laser
IEEE Photonics Journal, 2012 An all-optical switch based on an absorbing microring resonator laterally coupled to two waveguides is described theoretically using the coupling of modes in time formalism and numerically using the finite-difference time-domain method.

FEBS Letters, EarlyView.Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs
