Field Analysis And Electromagnetics

As photonics and materials science span new horizons, it is paramount that one's mathematical skills be honed. The primary objective of this book is to offer a review of vector calculus needed for the physical sciences and engineering.

ANSYS Inc. announced the availability of its leading provider of electromagnetic simulation software, ANSYS Electromagnetics 16.0, providing new, unique capabilities and enhancements that offer the most advanced approach to guide and optimize product designs.

This monograph is a comprehensive presentation of state-of-the-art methodologies that can dramatically enhance the efficiency of the finite-difference time-domain (FDTD) technique, the most popular electromagnetic field solver of the time-domain form of Maxwell's equations. These methodologies are aimed at optimally tailoring the computational resources needed for the wideband simulation of microwave and optical structures to their geometry, as well as the nature of the field solutions they support. That is achieved by the development of robust “adaptive meshing” approaches, which amount to varying the total number of unknown field quantities in the course of the simulation to adapt to temporally or spatially localized field features. While mesh adaptation is an extremely desirable FDTD feature, known to reduce simulation times by orders of magnitude, it is not always robust. The specific techniques presented in this book are characterized by stability and robustness. Therefore, they are excellent computer analysis and design (CAD) tools.
