In 1948 Tellegen [Philips Res. Rep. 3, 81 (1948)] suggested that an assembly of the lined up
electric-magnetic dipole twins can construct a new type of an electromagnetic material. Until …

Small ferrite-disk particles with magnetostatic (magneto-dipole) oscillations are
characterized by the topological-phase states—the vortex states. In a recently published …

Experimental evidence of the nonreciprocal Tellegen magnetoelectric effect is presented.
The measured particle consists of a small ferrite sphere and a small piece of a thin metal …

We investigate the photonic topological phases in Tellegen metamaterials characterized by
the antisymmetric magnetoelectric tensors with real-valued quantities. The underlying …

“Metamaterial” is the generic name to call structured materials whose sizes are smaller than
the wavelengths of our interest. So, they are approximately smaller than 1 μm for optical …

The nonreciprocal magnetoelectric effect, also known as the Tellegen effect, promises a
number of groundbreaking phenomena connected to fundamental (eg, electrodynamics of …

The birth of the subject of metamaterials, including many early contributions, is briefly
reviewed. More specifically, a relatively new topic, the properties of waves on magnetically …

A theory is presented combining effective-medium theory with that of magnetoinductive (MI)
waves propagating by virtue of coupling between the resonant elements. The resulting …

Electromagnetic (EM) metamaterials have become a field of intense research activities. This
paper presents a critical perspective of the field, with emphasis on fundamental concepts …

We show experimentally that active electromagnetic metamaterials are suitable for the
implementation of a large class of nonreciprocal media characterized by magnetoelectric …
