A miniaturized 2.4 GHz re-entrant cavity has been designed, manufactured and tested as a sensor for microfluidic compositional analysis. It has been fully evaluated experimentally with water and common solvents, namely methanol, ethanol, and chloroform, with excellent agreement with the expected behaviour predicted by the Debye model. The sensor's performance has also been assessed for analysis...

OBJECTIVES The purpose of this study was to evaluate the electroanatomic characteristics of left atrial tachycardia (AT) in a series of patients who underwent circumferential pulmonary vein ablation (CPVA) and to describe the ablation strategy and clinical outcome. BACKGROUND Circumferential pulmonary vein ablation is an effective treatment for atrial fibrillation. A potential midterm complic...

V-band Klystrons find applications in satellite communications and 5G technology. Here, we present a Klystron using radial re-entrant square cavities (RRSCs). The RRSCs are easy to fabricate, assemble, align, tune the operating frequency, which significant concerns V-band. We have optimized number of gap for best possible gain bandwidth. eigenmode particle-in-cell (PIC) simulation results CST m...
