Mathematics Used for Expressing Waves
Spherical waves, cylindrical waves and plane waves are the most basic wave forms. In general, more complicated wave forms can be expressed by the superposition of these three waves. In the present chapter, these waves are described phenomenologically while leaving the more rigorous expressions for later chapters. The symbols which are frequently used in the following chapters are summarized.
