6. Design of a 200Gbps externally modulated laser for opto-electronic integration
University essay from KTH/Tillämpad fysikAbstract : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

7. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants.

8. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.

10. Developing data processing program for a new radio magnetotelluric (RMT) instrument
University essay from Uppsala universitet/GeofysikAbstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE
