Novel vortex generator and mode converter for electron beams.
A mode converter for electron vortex beams is described. Numerical simulations, confirmed by experiment, show that the converter transforms a vortex beam with a topological charge m=±1 into beams closely resembling Hermite-Gaussian HG(10) and HG(01) modes. The converter can be used as a mode discriminator or filter for electron vortex beams. Combining the converter with a phase plate turns a pl...
متن کاملDual-Frequency Patch Antennas
Dual-hequency patch antennas may provide an alternative to large-bandwidth planar antennas, in applications in which large bandwidth is really needed for operating at two separate transmitreceive bands. When the two operating frequencies are far apart, a dual-frequency patch structure can be conceived to avoid the use of separate antennas. In this paper, a critical overview of possible solution...
متن کاملDouble Stator Induction Generator Model for Autonomous Operating Mode
Due to speed fluctuations of unregulated wind turbines, the terminal voltage may increase to dangerously high levels which have been reported to cause capacitor failure at wind farms. In this topic this paper examines a steady state performance analysis of stand-alone double stator induction generator self excited with two independents capacitors banks. An impedance approach based on double thr...
متن کاملX-Network with three antennas
Interference alignment is known to achieve the maximum sum DoF of 4M 3 in the 2 × 2 X-Network (i.e., twotransmitter (Tx) two-receiver (Rx) X-Network) with M antennas at each node, as demonstrated by Jafar and Shamai. Recently, an Alamouti code based transmission scheme, which we call the Li-Jafarkhani-Jafar (LJJ) scheme, was proposed for the 2×2 XNetwork with two antennas at each node. This sch...
متن کاملMultiplexed Millimeter Wave Communication with Dual Orbital Angular Momentum (OAM) Mode Antennas
Communications using the orbital angular momentum (OAM) of radio waves have attracted much attention in recent years. In this paper, a novel millimeter-wave dual OAM mode antenna is cleverly designed, using which a 60 GHz wireless communication link with two separate OAM channels is experimentally demonstrated. The main body of the dual OAM antenna is a traveling-wave ring resonator using two f...
