Complex Media
This chapter discusses complex media, which plays a big part in the late-twentieth-century technology revolution and is propagating with increasing speed and expanding front. Complex media are artificial materials exhibiting properties, based on their structure rather than their composition, which are superior to those in naturally existing materials. Nevertheless, there certainly do exist materials in nature displaying ‘exotic’ properties. Moreover, a discrimination between left and right has proven to be a fertile concept in the many branches of science that feed into electromagnetics: handedness is a term that is used extensively in the complex media literature. There are actually three notions of handedness of interest in electromagnetics, as this chapter shows.
