Metamaterials again? In the recent issue of the magazine "Physik in unserer Zeit" (only available in German) we report about the tailored properties of nanostructured materials for nonlinear optics.

Seminar for Bachelor students at the Department of Physics at Kasetsart University about recent research topics in physics.

Visit at the National Electronics and Computer Technology Center (NECTEC) in north Bangkok. The director of the Intelligent Devices and System Gruppe, Dr. Pongpan Chindaudom, explains the research activities.

First visit at the Rice Research Center in Pathumthani near Bangkok. Agricultural scientist Kunya Cheaupun explains the research problems for rice farming.

The IOP based website nanotechweb.org features a news article about our recent work of nonlinear metasurfaces.

Prof. Dr. Thomas Zentgraf and his team (University of Paderborn) has developed in collaboration with researchers from the University of Birmingham a new method to tailor the nonlinear optical properties of artificially structured material. With their new approach completely novel properties of materials can be obtained which cannot be implemented by naturally occurring materials.

We welcome our new group members Daniel Frese and Carsten Müller.

We recently achieved a new record for the efficiency of our metasurface holograms which are made only from a single layer of nanostructured plasmonic materials. With our new technique we were able to increase the efficiency by nearly 800% compared to previous hologram structures.

At Paderborn University’s New Year’s reception on 18 January 2015, the University Society awarded Franziska Zeuner the prize for outstanding final-year projects for the academic year 2013/2014 in the category of Engineering and Natural Sciences for her master's thesis on the coherent control of localised surface plasmons.

Prof. Lingling Huang from Beijing Institute of Technology in China is visiting our group for a two weeks period.

Basic research in physics using an innovative metamaterial made from nano-gold antennas – for the first time, the mesoscopic symmetry dependence of non-linear optical processes has been demonstrated.

Our group is further growing. We are welcome Felicitas Walter and Philip Georgi as new group members.

The Student Council of the Department of Physics at Paderborn University awarded Prof. Dr. Thomas Zentgraf the “Golden Chalk” prize for the best class in 2012/2013. The prize is awarded annually by the Physics Student Council to the lecturer who receives the highest ratings from students in the class evaluations.

Our group is organizing the 551. Heraeus-Seminar on "Active Nanoplasmonics and Metamaterial Dynamics" together with Prof. Ortwin Hess from Imperial College London in the “Physikzentrum” of the German Physical Society in Bad Honnef.

For the first time, researchers have succeeded in generating 3D images from nanostructured surfaces. To achieve this, our group used a special metamaterial containing nanoscale gold antennas to store information about an object.
