Abstract
Aspects of the subject disclosure may include, for example, a system for receiving a communication signal, generating an electromagnetic wave from the communication signal, and inducing the electromagnetic wave on a portion of a transmission medium having an insulation layer with a tapered end covering at least part of a conductor. Other embodiments are disclosed.
Claims20
A method, comprising:
- placing an insulation layer on a cable, the insulation layer having a slit which enables placement of the insulation layer on the cable;
- receiving, by a waveguide system including a waveguide structure, a first guided electromagnetic wave, the first guided electromagnetic wave being guided by the insulation layer, the insulation layer having a tapered end, a portion of the insulation layer having a substantially uniform outer diameter, the portion of the insulation layer being within the waveguide structure, the tapered end being outside of the waveguide structure, the insulation layer covering a first portion of the cable, and the insulation layer enabling a first radial dimension of a first field of the first guided electromagnetic wave to decrease as the first guided electromagnetic wave propagates longitudinally along the tapered end towards the waveguide structure;
- and
- generating, by the waveguide system, a first communication signal according to the first guided electromagnetic wave.

A system, comprising:
- an insulation material having a tapered end and a slit, the slit enabling placement of the insulation material on a portion of a cable;
- and
- a waveguide coupled to the insulation material to enable a first radial dimension of a first field of a first guided electromagnetic wave to decrease while the first guided electromagnetic wave propagates longitudinally along the tapered end towards the waveguide, a portion of the insulation material having a substantially uniform outer diameter, the portion of the insulation material being within the waveguide, the tapered end being outside of the waveguide, and the portion of the insulation material within the waveguide resulting in a gap between an outer surface of the insulation material and an inner surface of the waveguide.
A system, comprising:
- a dielectric material having a slit, the slit enabling placement of the dielectric material on a first portion of a cable, a first portion of the dielectric material having a substantially uniform longitudinal thickness, and a second portion of the dielectric material having a variable longitudinal thickness;
- a waveguide system including a waveguide structure coupled to the dielectric material;
- and
- circuitry configured to facilitate performance of operations, the operations comprising:
- causing the waveguide system to receive, via the waveguide structure, an electromagnetic wave guided by the dielectric material;
- and
- causing the waveguide system to generate, according to the electromagnetic wave, a communication signal, a field of the electromagnetic wave having a radial dimension that decreases as the electromagnetic wave propagates along the variable longitudinal thickness of the dielectric material away from a second portion of the cable not including the dielectric material and towards the waveguide structure, the first portion of the dielectric material being within the waveguide structure, and the second portion of the dielectric material being outside of the waveguide structure.
