The phonon is the physical particle representing mechanical vibration and is responsible for
the transmission of everyday sound and heat. Understanding and controlling the phononic …

Underpinned by the advent of metamaterials, transformation optics offers great versatility for
controlling electromagnetic waves to create materials with specially designed properties …

Metamaterial-based optical cloaks have thus far used volumetric distribution of the material
properties to gradually bend light and thereby obscure the cloaked region. Hence, they are …

Materials engineered at the micro-and nanometer scales have had a tremendous and
lasting impact in photonics and phononics. At much larger scales, natural soils civil …

We adapt tools of transformation optics, governed by a (elliptic) wave equation, to
thermodynamics, governed by the (parabolic) heat equation. We apply this new concept to …

It was recently shown theoretically that the time-dependent heat conduction equation is form
invariant under curvilinear coordinate transformations. Thus, in analogy to transformation …

Metamaterials are rationally designed man-made structures composed of functional building
blocks that are densely packed into an effective (crystalline) material. While metamaterials …

An object can be perceived and identified due to its unique scattering signature in various
physical fields, eg, optics, electromagnetics, acoustics, thermotics, etc. Analogous to wave …

Metamaterials and devices that provide cloaking functionalities have strong potential to
bring fundamental scientific and engineering developments including invisibility, sound and …

Metamaterials can exhibit electromagnetic and elastic characteristics beyond those found in
nature. In this work, we present a design of elastic metamaterial that exhibits multiple …
