In this thesis we study the properties of optical wire antennas. As experimental method for our investigations we use apertureless near-field optical microscopy. This technique achieves high spatial resolution well beyond the diffraction limit by utilizing ...
We study the trapping of nanoscopic objects in the near-field of plasmonic nanostructures and demonstrate experimentally that 10nm particles can be trapped in the 15nm gap of a dipole antenna. Applications for biosensing are discussed. ...

The enhancement of excitation and reemission of molecules in dose proximity to plasmonic nanostuctures is studied with special focus on the comparison between idealized and realistically shaped nonostructures. Numerical experiments show that for certain ap ...

In this work, we study how to use a plasmonic dipole antenna as a multifunctional nanodevice for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR) -based sensing and optical trapping. An analytical model is implemented ...

Recent advances in nanolithography have allowed shifting of the resonance frequency of antennas into the optical and visible wavelength range with potential applications, for example, in single molecule spectroscopy by fluorescence and directionality enhan ...
Surface enhanced Raman scattering (SERS) "hot spots" are the regions where the electromagnetic field is significantly enhanced, resulting in much greater SERS activity than other areas. Therefore, the engineering and characterization of "hot spots" have at ...
This paper presents an efficient modelling technique for partially reflective surface (PRS) antennas, based on the substitution of the actual detailed PRS by an uniform equivalent surface impedance. The properties of the equivalent surface are rigorously e ...
This paper reports on the design and fabrication of a fully integrated antenna beam steering concept for wireless sensor nodes. The conformal array circumcises four cube faces with a silicon core mounted on each face. Every silicon core represents a 2 by 1 ...
