Generation of High-Purity Millimeter-Wave Orbital Angular Momentum Modes Using Horn Antenna: Theory and Implementation
Twisted electromagnetic waves, of which the helical phase front is called orbital angular momentum (OAM), have been recently explored for quantum information, high speed communication and radar detections. In this context, generation of high purity waves carrying OAM is of great significance and challenge from low frequency band to optical area. Here, a novel strategy of mode combination method...
متن کاملFinal Report Project Name: Research on Novel High-power Microwave/millimeter Wave Sources and Report Documentation Page Research on Novel High-power Microwave/millimeter Wave Sources and Applications
Performance characteristics of a fundamental cyclotron harmonic, distributed-loss, TE01-mode gyrotron traveling-wave amplifier are studied theoretically. Absolute instabilities on both lower and higher order modes at the fundamental and second cyclotron harmonic frequencies present a severe limitation to the stable operating current and hence the device capability. General methods for stabilizi...
متن کاملElectron vortex beams with high quanta of orbital angular momentum.
Electron beams with helical wavefronts carrying orbital angular momentum are expected to provide new capabilities for electron microscopy and other applications. We used nanofabricated diffraction holograms in an electron microscope to produce multiple electron vortex beams with well-defined topological charge. Beams carrying quantized amounts of orbital angular momentum (up to 100ħ) per electr...
متن کاملCreating high-harmonic beams with controlled orbital angular momentum.
A beam with an angular-dependant phase Φ = ℓϕ about the beam axis carries an orbital angular momentum of ℓℏ per photon. Such beams are exploited to provide superresolution in microscopy. Creating extreme ultraviolet or soft-x-ray beams with controllable orbital angular momentum is a critical step towards extending superresolution to much higher spatial resolution. We show that orbital angular m...
متن کاملHigh-power millimeter-wave rotary joint.
The rotary joint is a useful microwave component that connects a fixed part to a rotatable part. This study systematically analyzes the effect of the discontinuity on the interface of a rotary joint for several waveguide modes. Simulation results indicate that the transmission of the TE(01) mode is independent of the geometry of the joint, and thus is ideal for such application. A rotary joint ...
