The group of Martin Wegener has produced the World's first Hall-effect reversal material, in the paper Experimental Evidence for Sign Reversal of the Hall Coefficient in Three-Dimensional Metamaterials based on a simplification of an interlocking ring design that in the papers Homogenization of the three-dimensional Hall effect and change of sign of the Hall-coefficient ( Hal.archives Version ) and Reversal of the Hall coefficient sign under homogenization , Marc Briane and I proved would reverse the Hall-effect back in 2007. This result (called by Wegener's group a "mind-boggling prediction") overturns the notion, found in many textbooks, that the Hall coefficient tells one the sign of the charge carrier. Inspiration for the geometry came from the chainmail artist Dylon Whyte and from joint work with Vincenzo Nesi. With D. Manceau we proved the reversal is impossible in two-dimensions.

A preview of what is inside the book can be found in these slides

One can find on arXiv five chapters: Analyticity of the Dirichlet-to-Neumann map for the time-harmonic Maxwell's equations with Maxence Cassier and Aaron Welters; Bounds for the response of viscoelastic composites under antiplane loadings in the time domain with Ornella Mattei; A rigorous approach to the field recursion method for two-component composites with isotropic phases with Maxence Cassier and Aaron Welters; The response of linear inhomogeneous systems to coupled fields: Bounds and perturbation expansions with Mordehai Milgrom; Superfunctions and the algebra of subspace collections and their association with rational functions of several complex variables.

Our work on ideal climbing ropes (also available on ArXiv ) made it to the front cover of climbing magazine . Direct link here . A once in a lifetime achievement!

See the news release by Paul Gabrielsen describing our work on analytic materials, New math tools for new materials , and the accompanying paper also available on ArXiv. This paper also reviews other exact solutions in inhomogeneous media and the subject of metamaterials, providing a proper historical perspective.

See below some of the many articles related to our work on cloaking. It could be that our 2006 paper
On the cloaking effects associated with anomalous localized resonance
(submitted in October 2005, * preceding the cloaking papers of Leonhardt and Pendry, Schurig, and Smith *)
was the first to introduce the word "cloaking" into the scientific literature,
outside computer science. With 12,815 downloads our paper
Quasistatic cloaking of two-dimensional polarizable discrete systems by anomalous resonance
was the
most downloaded paper in 2007
amongst all 12 journals of the Optical Society of America.

See the articles below related to pentamode materials a new class of material that we devised in the 1995 paper Which Elasticity Tensors are Realizable? also available here In 2012, before they built pentamodes the group of Wegener in the paper, ''Tailored 3D Mechanical Metamaterials Made by Dip-in Direct-Laser-Writing Optical Lithography'' wrote: ''In addition, the ''holy grail'' of mechanical materials, namely pentamode materials, that can be seen as the mother of all materials, might become accessible as well. Pentamodes, suggested by Milton and Cherkaev in 1995, are solids that behave like fluids with a very small effective shear modulus.''

Below is a figure from our landmark paper
* Optical and dielectric properties of partially resonant composites*
(with the most relevant text being highlighted) that marked the discovery of anomalous resonance and ghost sources

(see also the introduction of a draft paper, doi:10.13140/RG.2.1.1477.5283 ).

This later turned out to be the essential mechanism for explaining
the so-called
superlenses or perfect lenses,
for which Sir John Pendry received the
* Kavli Prize. *
.
Interestingly as shown in the paper
* Opaque perfect lenses*
for a point dipole source turned on within a distance d/2 of a "perfect lens" of thickness d and emitting
constant power the long-time transmission is zero not one! All the power gets pumped into the anomalously
resonant fields. In fact the source does not radiate behind the lens either: this is an example of
cloaking due to anomalous resonance, first discovered in the paper
* On the cloaking effects associated with anomalous localized resonance.*
