Abstract

The scattering of waves by small apertures and particles has been the source of numerous controversies over the last seventy years. I will discuss in this paper the similarities and differences in the behavior of different types of waves (light, electrons, and sound) when they are transmitted through subwavelength holes (either individual or arranged in periodic arrays) or when they are scattered by small particles. The opportunities and limitations of each of these types of waves will be analyzed and presented in the context of current metamaterials research. Article not available.
