Prof Irina Vendik Lectures at Stellenbosch University, 18 April 10h00-12h00, Room E347, E&E Engineering

10h00-10h45: Advances in microwave applications of metamaterial transmission line concepts:

• Equations for forward/backward  waves. Concept of left-handed transmission line (LH TL)
• General properties of right-handed and left-handed transmission lines (RH and LH TL) based on lumped components
• Examples of a realisation of metamaterial transmission lines
• Microwave devices based on a combination of RH and LH TL sections: filters, power divider-combiners, phase shifters
  

11h15-12h00: High temperature superconductors (HTS) for microwave filter design:

• Overview of microwave characteristics of HTS
• HTS microwave filter design procedure
• Examples of planar HTS filters

Global Navigation Satellite Systems:

Conventional Satellite technology has three applications: Communication, Remote Sensing and, Scientific Studies.  The latest one to add to this list is Satellite based Navigation also referred to as Satellite Navigation/Global Positioning System and lately termed as Global Navigation Satellite System (GNSS).  With the technological advancement taking place in mobile communications, controls, automobiles, aviation, geodesy, geological survey, military operations, precision farming, town planning, banking, weather predictions, power grid synchronization etc.,  in spite of each one having separate domain, there is one thing common in all of them for their future;  that  is the Precise-position, Timing and Velocity (PVT) – information, which can only be provided by Global Navigation Satellite System (GNSS).
Global Navigation Satellite System (GNSS) is a vast system of systems, providing global positioning, navigation and timing information to scores  of users in oceans, land, air and even in space.  The lecture module traces the history of navigation, evolution of navigation satellite systems, the three present constellations (GPS,GLONAS,GALILEO) and the world scenario in this direction including the S-BAS system.  The lecture module will also touch upon the basics of position, velocity and time measurements, various GNSS connected aspects, their applications and the technologies associated including the S-BAS system.
