The propagation of a Gaussian beam and its transformation through a lens has been well treated in previous literature.

The use of plastic coatings in optical-fiber technology is multifaceted.

Geometric frustration is a concept underlying many mysterious materials phenomena.

In the spring semester of 1990, the three of us organized and ran a new course at Princeton, called "Geometry and the Imagination" after the famous book by Hilbert and Cohn-Vosssen.

Temperature dependent weak localization is measured in metallic nanowires in a previously unexplored size regime down to width w=5 nm.

Turbulent flows disperse Lagrangian particles resulting not only in the growth of pairwise separations but, for sets of three or more particles, in a non-trivial dynamics of their configuration.

We study the classical model of expected utilities over a finite number of options, first rigorously defined by Von Neumann and Morgenstern.

We investigate using "photonic lanterns" as adiabatic mode converters for use in spatial-division multiplexing (SDM) systems to interface single-mode fibers to a multi-mode fiber.

The transit times of double heterojunction bipolar transistors (DHBTs) based on InGaAs/InP and GaAsSb/InP technologies are investigated by means of two different physical modeling techniques, speci

We describe a geometry-defined electrical interconnection medium based on a composite of small metal particles dispersed uniformly in an elastomer or adhesive matrix.
