Features: This book systematically studies the multi-scale theory of electromagnetic fields and waves and its applications. Its content is divided into four parts: The first part introduces the fundamental theory and research methods of electromagnetic fields and waves, the scattering characteristics of several typical targets for electromagnetic waves, and simulation results. The second part details the transformation relationships between typical coordinates and stretching coordinates. While ensuring the form invariance of the Maxwell equations, it studies the multi-scale theory of electromagnetic field quantities and related scale-invariant quantities, providing their physical significance, and also investigates the propagation characteristics of electromagnetic waves in stretching coordinates. The third part utilizes the multi-scale theory of electromagnetic fields to study the scattering and polarization characteristics of ellipsoidal targets for electromagnetic waves. The fourth part presents a model for the continuousization of discrete random media, derives the equivalent dielectric constant of rain media, and studies the propagation characteristics of pulse waves within them. Finally, it examines the influence of electromagnetic interactions between targets and backgrounds on the scattering characteristics of targets. This book features clear physical concepts, rigorous and concise theoretical derivations, and is primarily aimed at technical personnel engaged in research on electromagnetic scattering, wave propagation, radar systems, and stealth technology. It can also serve as a reference book for senior undergraduate and graduate students in related fields at universities.
