We consider lamellar gratings made of dielectric or lossy materials used in classical diffraction mounts. We show how the modal diffraction formulation may be generalized to deal with slanted lamellar gratings and illustrate ...

We extend the fictitious source superposition method in order to model linear defects in photonic woodpiles, and we use the method to model a waveguide that is created by changing either the radius or refractive index of ...

This paper presents the concept of a vibration control system in which motions of a continuous structure with piezoelectricsensors/actuators can be suppressed (or activated) through transforming mechanical energy to ...

We present a rigorous numerical study of the sub-wavelength focusing of electromagnetic waves using a time-reversal mirror, and show that the diffraction limit can be overcome in the optical domain.

We demonstrate the existence of a class of defects in 2D photonic crystals, for which the eigenstates depend only on the defect geometry, and not on details Re photonic crystal parameters or defect size.

In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, directivity, and polarization. In random lasers, which ...

We demonstrate by numerical simulation that the general features of the loss spectrum of photonic crystal fibres (PCF) with a kagome structure can be explained by simple models consisting of thin concentric hexagons or ...

An oil painting by Claude Monet, Port-Goulphar, Belle-Ile 1887 (collection of the Art Gallery of New South Wales), was examined to determine both the identity of the pigments used by the artist in this painting and his ...

We have used a Monte Carlo simulation for investigating the output of a digital instrument, of resolution half-width a, when its analogue input is a Gaussian signal. The digitizing process converts an actual mean to ...
