Variational methods for scattering: preserve reciprocity and bound error

Discover practical approaches to choosing approximations in scattering problems. This book shows how inserting a good field estimate into the variational expression can improve the scattered amplitude while keeping the reciprocity theorem intact. It explains that expanding the field in a basis and solving the resulting equations is equivalent to Galerkin’s method, and it guides you to pick function sets that yield real, reliable results. What you’ll learn

• How the variational principle links to Galerkin’s method and when they are interchangeable.
• Different strategies for constructing approximations that respect reciprocity.
• How to estimate accuracy and bound errors in practical calculations.
• Insights into low-frequency behavior and how to tailor trial functions for robust results.
