Microfluidics for reconfigurable electromagnetic metamaterials [PDF]
Applied Physics Letters, 2009 We propose microfluidics as a useful platform for reconfigurable electromagnetic metamaterials. Microfluidic split-ring resonators (MF-SRRs) are fabricated inside a flexible elastomeric material by employing rapid prototyping.

Electromagnetic energy density in hyperbolic metamaterials
Scientific Reports, 2022 AbstractWe present the theory of electromagnetic energy propagation through a dispersive and absorbing hyperbolic metamaterial (HMM). In this way, the permittivity tensor components of HMM (especially, nanowire HMM) may appear to be hopeless, but as a non-trivial step, we find that they can be cast into more transparent forms.

Metamaterial Electromagnetic Wave Absorbers [PDF]
Advanced Materials, 2012 AbstractThe advent of negative index materials has spawned extensive research into metamaterials over the past decade. Metamaterials are attractive not only for their exotic electromagnetic properties, but also their promise for applications. A particular branch–the metamaterial perfect absorber (MPA)–has garnered interest due to the fact that it can ...

Analysis of nonlinear electromagnetic metamaterials [PDF]
New Journal of Physics, 2010 We analyze the properties of a nonlinear metamaterial formed by integrating nonlinear components or materials into the capacitive regions of metamaterial elements. A straightforward homogenization procedure leads to general expressions for the nonlinear susceptibilities of the composite metamaterial medium.

Metamaterial Analog of Electromagnetically Induced Transparency [PDF]
Physical Review Letters, 2007 We present a new type of electromagnetic planar metamaterial that exhibit strong dispersion at a local minimum of losses and is believed to be the first metamaterial analog of electromagnetically induced transparency. We demonstrate that pulses propagating through such metamaterials experience considerable delay, whereas the thickness of the structure ...
