[PDF] Theory of dielectrics. Dielectric constants and dielectric loss (Oxford 1949) H. Frohlich

Now in its sixth printing (first in paperback), this book remains an excellent reference for anyone who works in applied physics, engineering, or chemistry. It gives a systematic account of the theory of dielectric properties, and the reader is assumed to have only an acquaintance with calculus, complemented by an elementary knowledge of atomic and molecular physics, statistical mechanics, and electrostatics.
