Laser Ablation Boosts Terahertz Emission
From almost instantaneous wireless transfer of huge amounts of data and easy detection of explosives, weapons, or harmful gases, to safe 3-D medical imaging and new advances in spectroscopy —technologies based on terahertz (THz) radiation, the electro-magnetic band with wavelengths from 0.1 to 1 mm, can transform science fiction into reality. However, scientists and engineers still do not have cheap and efficient solutions for mass production of THz-based devices.

The government has started to consider LTE services as a candidate for safety critical communications; specifically in group communication and proximity based services. This white paper describes the aspect of proximity based services involving the direct communication between two devices in LTE from a UE point of view. Network elements are described as far as they concern the UE. In addition to the message transmission and reception, a special emphasis is put on the synchronization between UEs and on the security for the message exchange.

Modeling Material Properties Based On Measurement
This webinar video presents how to use CST STUDIO SUITE® for a number of techniques for extracting material properties based on the measured S-parameters of simple geometry samples. The video will also discuss the importance of manufacturing technology in the extraction process in relation to the robustness of the specific technique. Important effects such as etch factor, over-etching, over-milling, metallization thickness, and the connection repeatability of low-cost end-launchers will also be addressed in real-world examples.
How Wireless Works
This is a short, animated video explaining what happens each time someone uses smartphones, tablets or other wireless devices.
Attenuation Made Easy
