Features: This book is based on the accumulated experience of long-term teaching reform in the Department of Electronic Engineering at Peking University. From the perspective of modern technology, light waves have become a practical band in electronics, and optoelectronic technologies such as amplification, oscillation, mixing, modulation, and demodulation have become increasingly mature. In this sense, optics should reflect the macroscopic wave theory in fundamental courses. Optics should be a continuation of Electromagnetism and a foundation of wave theory, but compared to sound waves and electromagnetic waves radiated by artificial devices, light waves have their own distinctive characteristics in polarization and coherence. Based on this understanding, the book starts with electromagnetic waves (vector waves), discusses interference and diffraction phenomena, explains the relationship between the near-field and far-field of wave sources, and includes examples and exercises involving basic waveguide components and various types of antennas and antenna arrays, aiming to guide readers to further understand the commonalities of waves in different bands. To adapt to the development of "Applied Optics," the book provides an introductory overview of optoelectronics. For this purpose, it qualitatively introduces optical nonlinear effects, explains the generation of lasers using a macroscopic feedback principle, and describes the modes of light waves in optical fibers through multi-beam interference within thin films. To align geometric optics with current application technologies, the book starts with Fermat's Principle to introduce secondary curved mirrors and lenses. Optical image information processing technology is a hot topic today, and the book includes a chapter for students to read. This book can serve as a fundamental physics textbook for science and engineering students in comprehensive universities, as well as a teaching or self-study reference for physics teachers in other higher education institutions and high schools.
