Plasmonic Enhanced Chiral Metamaterials

Alali F., Kim Y.H., Furlani E.P., University at Buffalo, US

Metamaterials are artificial materials that are engineered to produce various interesting phenomena such as negative refractivity and sub-diffraction-limit imaging. The majority of metamaterials for THz applications have been fabricated using “top-down” techniques. These methods tend [...]

Low Motional Impedance Bulk Acoustic Resonators Based on Metamaterials

Rottenberg X., Jansen R., Rochus V., Figeys B., Nauwelaers B., Tilmans H.A.C., IMEC, BE

This paper presents the implementation of propagating acoustic metamaterials in electrostatically transduced Bulk Acoustic Resonators (BARs) to tune by design their characteristic properties. Novel in this paper is our focus on lowering the observed motional [...]

Sub-wavelength metal nanostructure fabrication by parallel dip-pen nanolithography

Jang J-W, Nettikadan S., NanoInk Inc, US

Metal nanostructures in sub-wavelength scale have attracted interests in materials engineering and optics research. Metal nanostructures in sub-wavelength scale have been used as plasmonic diffraction gratings and negative index metamaterials. E-beam lithography has been commonly [...]
