Approximation of the Field Components of TE and TM Modes in Waveguides and Cavities with General Cross Section
This paper shows that the field components of TE and TM modes of waveguides and cavities with general cross section can be approximated by a power series consisting of a separeble solution and nonseparable solutions of Helmholtz wave equation corresponding to the rectangular waveguide.
On the Synthesis of Waveguides and Cavities Realized with Nonseparable Solutions of Helmholtz Wave Equation (Short Papers)
This short paper shows how nonseparable solutions of the Helmholtz wave equation can be used in the synthesis of waveguides and cavities with nonconventional cross section, and also investigates the attenuation and Q factor.
Influence of electric fields on friction electrification between metals and borosilicate glass
Abstract In a cylindrical geometry, electric fields were applied through the entire contact area between the sliding metal and the glass surface. The maximum electric charges developed on the metal were measured and plotted against the applied voltage producing the field. The metals were high-purity nickel and gold. The borosilicate glass was Pyrex, brand 7740. The experiments with nickel, which has a work function greater than that of the glass, were performed in 10 −7 mm Hg vacuum. The experiments with gold, with a work function smaller than that of glass, were carried out in air at atmospheric pressure. The results show that: 1. 1) There is both asymmetry and a reversed slope portion in the charge vs. voltage plot. 2. 2) For a certain range of reversing fields, the electric charge developed on the nickel is always negative and the charge on gold is always positive.
