1. A device, comprising:

  • a transmitter that facilitates generation of an electromagnetic wave;

    a dielectric material; and

    a coupler that facilitates receiving the electromagnetic wave from the transmitter,wherein the dielectric material is disposed on a first portion of a surface of a transmission medium,wherein a tapered region of the dielectric material has a variable dielectric constant,wherein the coupler is coupled to a portion of the dielectric material,wherein the coupler facilitates guiding the electromagnetic wave to the tapered region and the transmission medium, andwherein the variable dielectric constant of the tapered region facilitates reducing a radiation of the electromagnetic wave as the electromagnetic wave propagates to a second portion of the surface of the transmission medium.
