This volume is intended to serve as a general text on wave propagation for senior undergraduates and fifirst-year graduate students in physics, applied physics, engineering, materials sciences, optics, and other related scientifific disciplines. We also hope that it will be useful for the many scientists working in different areas of wave propagation.
The importance of waves in our everyday life can hardly be overestimated. Waves are everywhere. Most of the information we receive comes to us in the form of waves. We see and hear through waves. We transmit and receive information through waves. We rely onwaves to bring us music, television, Email, and wireless communications. We can cook with waves, talk to each other, and see things because of waves. Waves are also used in medicine; and in industry to examine objects, such as planes, for cracks and stress. Waves in periodic media usually exhibit some common characteristics. The most important is the possible appearance of stop bands (also called gaps) separating pass bands (also called bands). This means that the frequency axis may be divided into alternating regions of gaps and bands.
