Opis: Surface Impedance Boundary Conditions - Sergey V. Yuferev, Nathan Ida, S Yuferev

Surface Impedance Boundary Conditions is perhaps the first effort to formalize the concept of SIBC or to extend it to higher orders by providing a comprehensive, consistent, and thorough approach to the subject. The product of nearly 12 years of research on surface impedance, this book takes the mystery out of the largely overlooked SIBC. It provides an understanding that will help practitioners select, use, and develop these efficient modeling tools for their own applications. Use of SIBC has often been viewed as an esoteric issue, and they have been applied in a very limited way, incorporated in computation as an ad hoc means of simplifying the treatment for specific problems. Apply a Surface Impedance "Toolbox" to Develop SIBCs for Any Application The book not only outlines the need for SIBC but also offers a simple, systematic method for constructing SIBC of any order based on a perturbation approach. The formulation of the SIBC within common numerical techniques-such as the boundary integral equations method, the finite element method, and the finite difference method-is discussed in detail and elucidated with specific examples. Since SIBC are often shunned because their implementation usually requires extensive modification of existing software, the authors have mitigated this problem by developing SIBCs, which can be incorporated within existing software without system modification. The authors also present: Conditions of applicability, and errors to be expected from SIBC inclusion Analysis of theoretical arguments and mathematical relationships Well-known numerical techniques and formulations of SIBC A practical set of guidelines for evaluating SIBC feasibility and maximum errors their use will produce A careful mix of theory and practical aspects, this is an excellent tool to help anyone acquire a solid grasp of SIBC and maximize their implementation potential.Classical Surface Impedance Boundary Conditions Skin Effect Approximation SIBCs of the Order of Leontovich's Approximation High-Order SIBCs Rytov's Approach References General Perturbation Approach to Derivation of Surface Impedance Boundary Conditions Local Coordinates Perturbation Technique Tangential Components Normal Components Normal Derivatives Components of the Curl Operator Surface Impedance "Toolbox" Concept Numerical Example Appendix SIBCs in Terms of Various Formalisms Basic Equations Electric Field-Magnetic Field Formalism Magnetic Scalar Potential Formalism Magnetic Vector Potential Formalism Common Representation of Various SIBCs Using a Surface Impedance Function Surface Impedance near Corners and Edges Calculation of the Electromagnetic Field Characteristics in the Conductor's Skin Layer Distributions across the Skin Layer Resistance and Internal Inductance Forces Acting on the Conductor Derivation of SIBCs for Nonlinear and Nonhomogeneous Problems Coupled Electromagnetic-Thermal Problems Magnetic Materials Nonhomogeneous Conductors Implementation of SIBCs for the Boundary Integral Equation Method: Low-Frequency Problems Two-Dimensional Problems Three-Dimensional Problems Properties of the Surface Impedance Function Boundary Element Formulations for Two- and Three-Dimensional Problems in Invariant Form Numerical Examples Quasi-Three-Dimensional Integro-Differential Formulation for Symmetric Systems of Conductors Implementation of SIBCs for the Boundary Integral Equation Method: High-Frequency Problems Integral Representations of High-Frequency Electromagnetic Fields SIBCs for Lossy Dielectrics Direct Implementation of SIBCs into the Surface Integral Equations Implementation Using the Perturbation Technique Numerical Example Appendix Implementation of SIBCs for Volume Discretization Methods Statement of the Problem Finite-Difference Time-Domain Method Finite Integration Technique Finite-Element Method Appendix Application and Experimental Validation of the SIBC Concept Selection of the Surface Impedance Boundary Conditions for a Given Problem Experimental Validation of SIBCs Appendix A: Review of Numerical Methods Index
