▎ 摘　　要

NOVELTY - Semiconductor device comprises at least one conductive floating gates (204) superimposed on and/or embedded within a conducting channel (203) for managing electromagnetic radiation within the device, where each conductive floating gate has a size smaller than a mean free path of electrons in the semiconductor device. USE - The semiconductor device is useful for managing electromagnetic waves (claimed). ADVANTAGE - The device: improves the coupling efficiency; and eliminates the parasitic gate resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for managing electromagnetic waves in a semiconductor device. DESCRIPTION OF DRAWING(S) - The figure shows a block schematics view of a semiconductor device having at least one asymmetrical conductive floating gates in a one or two-dimensional array superimposed on a conducting channel.
