How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

Abstract: In this article, we propose a method based on the aperture antennas theory to understand the limitations of orbital angular momentum (OAM) antennas in far-field links. Additional insight is ...

Combined with THz, the newly exploited physical layer transmission dimension orbital angular momentum (OAM) that multiplexes a set of orthogonal modes on the same frequency channel, can unleash its ...

Abstract: We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional ...

Abstract: In this paper, a multifunctional scattering antenna array has been proposed to generate orbital angular momentum (OAM) vortex scattering wave and meanwhile reduce antenna radar cross section ...

Leaders with Savage & Associates say their organization was founded on philanthropy, so the opportunity to give back to local pediatric patients is a no brainer.

Abstract: Vortex beams carrying orbital angular momentum (OAM) are extensively studied owing to its potential to expand channel capacity of microwave and optical communication. By utilizing the ...

The momentum of an object is the product of its mass and its velocity. There is an equivalent law for rotating objects. A rotating object tends to remain rotating with a constant angular momentum ...

You will have to move with the wheel as it slowly turns in a circle. What’s Going On? A rotating bicycle wheel has angular momentum, which is a property involving the speed of rotation, the mass of ...

The structure and morphology of as-prepared Co3O4 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The TEM ...
