In this work the usage of a composite right/lefthanded (CRLH) metamaterial transmission line resonator as a transmit/receive coil for 7 Tesla magnetic resonance imaging (MRI) is investigated. On the basis of zeroth-order resonant antennas (ZORAs) a zeroth-order resonant coil (ZORC) was designed. Due to a constant current distribution along the element, a(More)
Ongoing violent conflicts in Central Africa are fueled by illegal mining and trading of tantalum, tin, and tungsten ores. The credibility of document-based traceability systems can be improved by an analytical fingerprint applied as an independent method to confirm or doubt the documented origin of ore minerals. Wolframite (Fe,Mn)WO4 is the most important(More)
In the research of neural diseases like epilepsy and schizophrenia genetic mouse models play a very important role. Dysfunctions during early brain development might cause these diseases. The analysis of the brain signals is the key to understand this process and develop treatments. To enable the acquisition of brain signals from neonatal mice, an(More)
