The book of the American author outlines general issues of the crystalline structure and lattice dynamics, considers the most significant features of metals and semiconductors, as well as the dielectric and magnetic properties of solids and their resonance phenomena. The book was written with great pedagogical skill; tasks placed at the end of each chapter complement the text and can be used in self-study of the subject. The book is intended for physics and metal students beginning their acquaintance with solid state physics. It will also benefit researchers and engineers who want to study solid state physics on their own or expand their knowledge.
