The field of computational electromagnetics (CEM) has experienced significant growth in recent years, driven by the increasing demand for accurate and efficient solutions to complex electromagnetic problems. This fourth edition of the text reflects this trend and incorporates numerous advances and refinements made in the field.

One of the most notable improvements in this edition is the enhancement of the standard algorithm for the finite-difference time-domain (FDTD) method. The FDTD method is a widely used technique for solving electromagnetic problems, particularly those involving complex structures or large domains. The improved algorithm in this edition has been shown to provide more accurate results with reduced computational time, making it an even more powerful tool for CEM applications.

Another significant improvement is the treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. Absorbing boundary conditions are used to model surfaces that do not reflect or transmit electromagnetic waves, such as metal or dielectric materials. In the past, these conditions were often treated poorly, leading to inaccurate results. The updated treatment in this edition ensures that absorbing boundary conditions are correctly implemented, resulting in more reliable and accurate solutions.

In addition to these improvements, the fourth edition of the text includes new homework problems in each chapter. These problems are designed to help readers apply the concepts and techniques learned in the text and to develop their problem-solving skills. Each chapter is also updated with the current trends in CEM, ensuring that readers are familiar with the latest developments in the field.

Furthermore, the text includes a new appendix on CEM codes, which covers both commercial and free codes available for use in CEM applications. This appendix is a valuable resource for researchers and practitioners who need to implement CEM solutions in their work.

Overall, this fourth edition of the text is an excellent resource for anyone interested in computational electromagnetics. It provides a comprehensive and up-to-date introduction to the field, incorporating advances and refinements made in recent years. With its clear and concise writing style, the text is accessible to students and professionals alike, and it will undoubtedly serve as a valuable guide for years to come.
