• PREFACE TO THE FIRST EDITION

• CONTENTS

It is the aim of this book to describe the optical properties of surfaces with a thickness small compared to the wavelength of the incident light. The emphasis will be on two kinds of surfaces. The first kind consists of a film of discrete islands, small compared to the wavelength, attached to a flat substrate. An important example of such films are metallic films. The second kind is the rough surface. In that case the surface resembles a landscape with hills and valleys. The height is again small compared to the wavelength of the light. In the second edition a chapter has been added on the reflection from a gyrotropic medium…
