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: 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 ...

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.

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 ...
