Tactile displays have a wide range of applications in assistive technology, prosthetics, and rehabilitation. Vibrotactile stimulation shows potential to be integrated into wearable devices because of its small size, low power consumption, and relative fast responding speed. In this paper, experiments investigating vibrotactile minimal detectable level, just noticeable difference, and two point discrimination...
Partial Discharge (PD) measurements are considered as a powerful technique for testing and monitoring the condition of high-voltage (HV) insulations. PD diagnostics is generally accepted as an early breakdown indicator, which is also reflected in numerous standards. In the present contribution, the authors describe the fundamentally different propagation mechanisms of electrical impulses in the conventional...

In this conference paper, we propose asymmetric single split resonators, which feature a very high Q-factor and a small electrical size, as unit cells for terahertz frequency selective surface applications such as filters or thin-film sensors. To benchmark the performance of these resonators, we compare the proposed single split asymmetric structures to their double split counterparts with the same...
We propose a coplanar bandpass filter with a very compact electrical size. The design comprises a cascade of a regular and a complementary multiple turn rectangular spiral resonator. This concept is especially appealing to applications, where miniaturization and compatibility with planar millimeter wave technology are key issues.
Laser light at 780 nm is coupled into a resonator with a finesse of 4.5 x 105, and the output light is detected by a photomultiplier and a camera. A part of the measured frequency spectrum of the resonator is shown in this paper. Two sets of modes are observed at distinct frequencies with the set of modes depending on the polarization of the uncoupled light, confirming the predicted spin-orbit coupling...
In this conference paper, we discuss the spectral response of new rectangular asymmetric resonators and compare it to the characteristics of conventional circular structures. The rectangular design offers a miniaturization of more than 20% and features an improved transmission roll-off. Moreover, tips at the end of the resonator arms confine the electric field into a small area. Especially frequency...
In this paper, a new concept for bandstop filters based on complementary split rectangle resonators etched into a single metal layer is proposed. Using equally length complementary resonators is the key behind the concept. This results an extreme improvement of the first spurious stopband with smooth insertion loss over a very wide bandwidth. The effect of adding slots in the proximity of the resonators...
This paper proposes a miniaturized rectangular asymmetric double split resonator. Furthermore, a modified electrode shaping for enhanced field confinement in the gap is suggested to further increase the sensitivity for thin-film sensing.
Using THz time-domain and FTIR spectroscopy we measure the far-infrared absorption spectra of various biomolecular crystals with different numbers of hydrogen bonds of different strengths. The experimental data are compared to density functional theory calculations.
