How to Derive the Schrodinger Equation
David W. Ward, Sabine M. Volkmer
We illustrate a simple derivation of the Schrodinger equation, which requires only knowledge of the electromagnetic wave equation and the basics of Einstein's special theory of rel…
Polaritonic materials fabricated and tested with ultrashort-pulse lasers
David W. Ward, Eric R. Statz, Thomas Feurer +1
Using femtosecond laser machining, we have fabricated photonic bandgap materials that influence propagation of phonon-polaritons in ferroelectric crystals. Broadband polaritons wer…
Polaritonics in complex structures: Confinement, bandgap materials, and coherent control
David W. Ward, Eric Statz, Jaime D. Beers +6
We report on the design, fabrication, and testing of ferroelectric patterned materials in the guided-wave and polaritonic regime. We demonstrate their functionality and exploit pol…
On the physical origins of the negative index of refraction
David W. Ward, Keith A. Nelson, Kevin J. Webb
The physical origins of negative refractive index are derived from a dilute microscopic model, producing a result that is generalized to the dense condensed phase limit. In particu…
Finite Difference Time Domain (FDTD) Simulations of Electromagnetic Wave Propagation Using a Spreadsheet
David W. Ward, Keith A. Nelson
We describe a simple and intuitive implementation of the method of finite difference time domain simulations for propagating electromagnetic waves using the simplest possible tools…
Simulation of Phonon-Polariton Generation and Propagation in Ferroelectric LiNbO3 Crystals
David W. Ward, Eric Statz, Nikolay Stoyanov +1
We simulate propagation of phonon-polaritons (admixtures of polar lattice vibrations and electromagnetic waves) in ferroelectric LiNbO3 with a model that consists of a spatially pe…
