Degrading cable connections are a major problem in the medium-voltage grid. Early failure detection is therefore very important. In this paper, a flexible, small-sized, self-sufficient wireless monitoring system for medium voltage cable joints is pre

This contribution presents a Fabry-Perot Interferometer (FPI) for the visible spectral range from 555 nm to 585 nm. Two approaches for the FPI reflectors are investigated: a (TiO 2 /PE-SiO 2 )³ Bragg reflector consisting of 55 nm TiO 2 and 97 nm PE-

Miniaturized spectrometry systems are achievable e.g. by the use of MEMS based tunable Fabry-Perot Interferometers (FPI) as wavelength selective filter elements. Main part of a FPI is the reflector which is usually realized as a stack of alternating

A tunable MEMS Fabry-Perot infrared filter with subwavelength structured reflectors substituting state of the art Bragg reflectors is presented. The reflectors consist of a disc resonator array arranged on a membrane carrier. The subwavelength struct
