1. Millimeter-Wave Photonics: Signal Sources and Transmission Links
Sammanfattning : With the use of higher and higher frequencies in a number of current and future wireless millimeter-wave applications it is beneficial to use photonics for several reasons. The use of optical fibers is an advantageous way to transport millimeter-waves in terms of loss, mechanical flexibility, weight, and insensitivity to electromagnetic interference. LÄS MER
2. A multiwavelength approach to solar chromospheric heating : New insights from the millimeter continuum
Sammanfattning : The chromosphere is an intermediate layer of the Sun's atmosphere where radiative equilibrium breaks down. The standard chromospheric diagnostics such as the Mg II h and k and Ca II H and K spectral lines are formed under nonlocal thermodynamic equilibrium (NLTE) and they are only partially sensitive to the local conditions.

3. Flip-Chip Interconnect for Millimeter-Wave Packaging Applications
Sammanfattning : In recent years, with the demands for wireless communication systems increas rapidly, the operating frequency for the portable wireless is moving toward millimeter-waves. Millimeter-wave wireless communication systems require not only suitable functional IC components but also competent package with low cost and good interconnect performance. LÄS MER
4. Gap Waveguide Technology for Millimeter Wave Applications and Integration with Antennas
Sammanfattning : The increasing advance of short range wireless communications requiring high data rates and the lack of available spectrum have driven researchers and industry to move towards higher frequencies, in particular to the millimeter wave range. The opening of this wide portion of free spectrum has risen a large interest in developing mm-wave communication systems for commercial applications. LÄS MER
5. Enabling Solutions for Integration and Interconnectivity in Millimeter-wave and Terahertz Systems
Sammanfattning : Recently, Terahertz (THz) systems have witnessed increasing attention due to the continuous need for high data rate transmission which is mainly driven by next-generation telecommunication and imaging systems. In that regard, the THz range emerged as a potential domain suitable for realizing such systems by providing a wide bandwidth capable of achieving and meeting the market requirements. LÄS MER
