Within a time span of 15 years, acoustic metamaterials have emerged from academic
curiosity to become an active field driven by scientific discoveries and diverse application …

Artificially engineered metamaterials are now demonstrating unprecedented
electromagnetic properties that cannot be obtained with naturally occurring materials. In …

In 1873, Ernst Abbe discovered what was to become a well-known paradigm: the inability of
a lens-based optical microscope to discern details that are closer together than half of the …

The imaging resolution of conventional lenses is limited by diffraction. Artificially engineered
metamaterials now offer the possibility of building a superlens that overcomes this limit. We …

This is a review on theoretical and experimental studies on dielectric microcavities, which
play a significant role in fundamental and applied research. The basic concepts and theories …

Diffraction of light prevents optical microscopes from having spatial resolution beyond a
value comparable to the wavelength of the probing light. This essentially means that visible …

An optical metamaterial is a composite in which subwavelength features, rather than the
constituent materials, control the macroscopic electromagnetic properties of the material …

Metamaterials is a young subject born in the 21st century. It is concerned with artificial
materials which can have electrical and magnetic properties difficult or impossible to find in …

Fluorescence spectroscopy is widely used in biological research. Until recently, essentially
all fluorescence experiments were performed using optical energy which has radiated to the …
