2. 1. Applications of Microwave Heating of Foods

   Author : Birgitta Raaholt; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

   Abstract : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. READ MORE

4. 2. Engineering and detecting microwave photons

   Author : Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwave photon detection; Quantum optics; open quantum systems.; tunable cavity; cross-Kerr effect; circuit QED;

   Abstract : Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. READ MORE

6. 4. Microwave Breakdown in Inhomogeneous Fields

   Author : Joel Rasch; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; corona; inhomogeneous fields; Microwave breakdown; multipactor;

   Abstract : Microwave breakdown continues to be a risk in many applications involving the transmission and reception of microwave frequency signals. Satellite communication is especially interesting from the research point of view because of the extreme costs, and limited testing possibilities. READ MORE

7. 5. From Macroscopic to Microscopic Dynamics of Superconducting Cavities

   Abstract : Superconducting (SC) radio frequency (RF) cavities are at the heart of many large-scale particle accelerators such as the European Spallation Source (ESS), the X-ray Free Electron Laser (XFEL), the Linac Coherent Light Source (LCLS)-II and the proposed International Linear Collider (ILC). The SC cavities are essentially resonant structures with very high intrinsic quality factors (Q0) of the order of 1010. READ MORE
