In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

This review aims to summarise the progress in some materials and structures for
electromagnetic applications, such as microwave absorption, electric shielding and antenna …

We look at four length scales associated with the surface plasmon–polariton (SPP) modes in
the visible and near-infrared. We examine some of the consequences of these length scales …

We experimentally demonstrate an infrared broadband absorber based on an array of
nanostrip antennas of several different sizes. The broadband property is due to the collective …

Liquid-crystal devices are a promising cheap alternative for terahertz light modulation, albeit
they suffer from problems associated with thick cells. Here we describe a few-micron-thick …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

We present an experimental and theoretical study of the optical transmission of a thin metal
screen perforated by two subwavelength slits, separated by many optical wavelengths. The …

We present an experimental and theoretical study of the optical properties of metal-dielectric-
metal structures with patterned top metallic surfaces, in the THz frequency range. When the …

This paper reviews the main physical aspects involved in plasmonic devices, which are
considered as a route to subwavelength devices and represents one of the most studied …

We have demonstrated that a metal-dielectric-metal microcavity combined with quantum
well intersubband transitions is an ideal system for the generation of cavity polariton states …
