Excitonic mechanism of the photoinduced surface restructuring of copper
An explanation for the photoinduced reconstruction of Cu single-crystal surfaces that was observed by Ernst et al. [Science 279, 679 (1998)] under the influence of visible light is proposed. It is sug...

We propose and design a new type of nonlinear metamaterials exhibiting a resonant electric response at microwave frequencies. By introducing a varactor diode as a nonlinear element within each resonator, we are able to shift the frequency of the electric mode stop band by changing the incident power without affecting the magnetic response. These elements could be combined with the previously developed nonlinear magnetic metamaterials in order to create negative index media with a control over both electric and magnetic nonlinearities.

- For most orientations of the resonators relative to the incident wavevector, retardation effects will cause some phase shift in the fields across each element, thus complete cancellation of the dipole moment may not occur at the resonant frequency.
