Using Critical Reflection to effect Dispositional Change toward Critical Thinking and Gain Insight into Student Learning

The purpose of this research roundtable is to discuss the use of Brookfield’s Critical Incident Questionnaire to effect dispositional change in students toward critical thinking, gain greater instructor insight, and improve instruction. My preliminary, and future, work in this area derives from experience with undergraduate students taking a general education science course

Power Pull: an unconditionally stable active Load-Pull measurement system

For today's communication circuits optimum operational conditions for almost every Tx power amplifier is one of the most important parameters. Only this will offer maximum power added efficiency and output power. For the experimental determination of these conditions load-pull measurements are the best solution. To compensate losses of the setup for on-wafer measurements an active load-pull measurement system is required. The Power Pull load-pull system combines all advantages of active load-pull measurements with an absolute stable configuration. It prevents oscillation of the measurement setup as well as of the transistor under test for large signal operation. Therefore, this configuration easily allows the complete characterization of transistors for optimum matching within power amplifiers

Liquid Crystal-Reconfigurable Antenna Concepts for Space Applications at Microwave and Millimeter Waves

Novel approaches of tunable devices for millimeter wave applications based on liquid crystal (LC) are presented. In the first part of the paper, a novel concept of a tunable LC phase shifter realized in Low Temperature Cofired Ceramics technology is shown while the second part of the paper deals with a tunable high-gain antenna based on an LC tunable reflectarray. The reflectarray features continuously beam scanning in between ±25∘. Also first investigations on radiation hardness of LCs are carried out, indicating that LCs might be suitable for space applications
