TL;DR: In this article, the ridge structure in the broad wall of the slotted waveguide is used to increase the current path, which makes the antenna achieving the appropriate phase difference of orthogonal electric fields within narrow antenna width.

TL;DR: In this paper, the authors proposed a circularly polarised horn antenna with large side length ratio and 45° deflection structure and rectangular aperture with large aspect ratio to achieve wideband circular polarisation radiation in small dimension.

TL;DR: In this paper, the lumped reaction engineering approach (L-REA) is implemented to model wood drying under rapid periodically changed drying air temperature and humidity with high number of cycles of intermittency.

TL;DR: In this article, a plasma-filled diode was used as a model for the interaction space in a virtual cathode oscillator (VCO) (vircator), and it was shown that depending on the separation of the electrodes, the initial ion/electron ratio /spl alpha/spl circ/, and the load Z/spl sub-circ/sub l/subl/, the system may exhibit a cascade of bifurcations leading to chaos.

TL;DR: This paper describes the analysis of a 42 GHz gyrotron with the 3D PIC simulation tool CST PARTICLE STUDIO® and results show good agreement to MAGIC simulations.
