Chapter 7 Dispersion, Impedance, Reflection, and Transmission
... the greater the temporal step and hence the more quickly a simulation advances (i.e., each update represents a greater advance in time). Second, the larger the Courant number, the smaller the dispersion error. In one dimension a Courant number of unity is the greatest possible and, since there is no ...

... solid has uniform composition, however, at equilibrium, this condition must be satisfied even if the solid changes properties over some lateral dimension due to extrinsic doping or even gross changes in composition. Indeed, this behavior is fundamental to any understanding of contacts and junctions ...

Meta-tarbernite 1, its physical properties and relation to Torbernite.
... The occurrence of natural crystalline material removes all doubt that meta-torbernite I has a perfect crystalline structm'e. In the transition from torbernite we have, therefore, a morphotropic change that can be brought about, not only by a re-growth in the new form, but by the direct removal of w ...

During this time, we see that electrons are accelerated simultaneously with the ions. In particular, after 0907:30 UT at CL1 and 0908:35 UT at CL4, ...

Density of states
.svg?width=300)
In solid-state and condensed matter physics, the density of states (DOS) of a system describes the number of states per interval of energy at each energy level that are available to be occupied. Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous. A high DOS at a specific energy level means that there are many states available for occupation. A DOS of zero means that no states can be occupied at that energy level. In general a DOS is an average over the space and time domains occupied by the system. Localvariations, most often due to distortions of the original system, are often called local density of states (LDOS). If the DOS of an undisturbedsystem is zero, the LDOS can locally be non-zero due to the presence of a local potential.
