Abstract
A one-dimensional nanostructure multi-port coupler () is provided for use in an RF device (). The coupler () includes a first plurality of one-dimensional nanostructures () aligned substantially in a first direction () and coupled between the input () and first output ('), and a second plurality of one-dimensional nanostructures () substantially aligned in a second direction (), coupled to a second output (), and disposed contiguous to the first plurality of one-dimensional nanostructures (). The first and second plurality of one-dimensional nanostructures () may comprise first and second contiguous planes. The amount of RF energy coupled may be controlled by varying the width, density, diameter, and type of one of the plurality of one-dimensional nanostructures () versus the other. The amount of RF energy coupled may also be controlled by varying the angle between the first and second plurality of one-dimensional nanostructures () and by disposing a dielectric material () therebetween.
