High accuracy terahertz time-domain system for reliable characterization of photoconducting antennas
Publikováno v:
Microwave and Optical Technology Letters. 59:468-472
We report on a terahertz (THz) time-domain system to characterize photoconductive THz emitters and detectors, that is designed for highest reproducibility. This system is excellently suited for studying the performance of THz sources and detectors in

A terahertz amplitude switching device is proposed which allows for the efficient manipulation of sharp transmission bands. The switching concept is based on the thermally triggered insulator-to-metal transition of a thin vanadium dioxide layer, plac

A novel conceptual design methodology for strongly interacting metamaterials allows an ultrahigh angular sensitivity. Among others, this methodology enables precise sensing of the wave vector or the exclusion of unwanted directional radiation compone

The use of laser ablation of a thin metal film, which allows for rapid prototyping of various free-standing terahertz devices, is reported. The technique will provide a simple way to fabricate devices without complicated photolithography procedures.

We present a numerical method to determine the volumetric water content of leaves from transmission terahertz time-domain spectroscopy data. The method is based on iterative optimization of parameters of an effective medium model for vegetative tissu

We demonstrate pulsed THz emission and detection in low temperature (LT) MBE grown Be-doped InGaAs/InAlAs multi-nanolayer structures for an excitation wavelength of 1030 nm. We obtained spectra with a bandwidth of up to 3 THz. Furthermore, we perform

The feasibility of THz time-domain spectroscopy for monitoring the leaf water content of plants has been shown in earlier publications. Here, we present extensive measurement series on different plant species. Our measurements show that the behavior

We demonstrate a refractive index sensor for liquid samples for the THz range. The sensor presents a refractive index dependent resonance which shifts in frequency at a rate that exceeds 500 GHz/RIU. The simple structure of the sensor and the low liq
