Lauber et al [1] experimentally studied the pattern of Berry phases that emerges when a microwave cavity is cyclically deformed around a rectangular shape. Standing electromagnetic waves in the cavity can be mapped and the “wave functions” followed through the cyclic deformation to measure the Berry phase. Apart from the Berry phases, which were primarily of interest in ref [1], those authors a...

Understanding electromagnetic wave phenomena is very important to be able to design RF cavities such as for atmospheric microwave plasma torch, microwave vacuum oscillator/amplifier, and charged-particle accelerator. This chapter deals with some electromagnetic wave equations to show applications to develop the analytic design formula for the cavity. For the initial and crude design parameter, ...

Natural convection in an inclined rectangular cavity filled with air is numerically investigated. The cavity is heated and cooled along the active walls whereas the two other walls of the cavity are adiabatic. Entropy generation due to heat transfer and fluid friction has been determined in transient state for laminar natural convection by solving numerically: the continuity, momentum and energ...
