Abstract

Aspects of the subject disclosure may include, for example, a transmission medium that includes a dielectric core comprising a plurality of rigid dielectric members configured to propagate guided electromagnetic waves. A dielectric cladding is disposed on at least a portion of an outer surface of the first dielectric core. Other embodiments are disclosed.

First claim

What is claimed is:

1. A transmission medium, comprising:
a dielectric core comprising a plurality of rigid dielectric members coupled together in a ball and socket configuration that is configured to propagate guided electromagnetic waves at non-optical frequencies; and
a dielectric cladding disposed on at least a portion of an outer surface of the dielectric core.

2. The transmission medium of claim 1 , wherein the dielectric core has a first dielectric constant that exceeds a second dielectric constant of the dielectric cladding.

3. The transmission medium of claim 2 , wherein the first dielectric constant exceeding the second dielectric constant causes the guided electromagnetic waves to be bound to the dielectric core.

4. The transmission medium of claim 1 , wherein the plurality of rigid dielectric members are arranged end to end in the ball and socket configuration.

5. The transmission medium of claim 1 , wherein the plurality of rigid dielectric members are arranged in the ball and socket configuration to propagate the guided electromagnetic waves in a longitudinal sequence.

6. The transmission medium of claim 5 , wherein the plurality of rigid dielectric members each includes a first end configured to mate with a previous one of the plurality of rigid dielectric members in the longitudinal sequence and a second end configured to mate with a next one of the plurality of rigid dielectric members in the longitudinal sequence.

7. The transmission medium of claim 6 wherein each one of the first end and the second end are configured as one of: a ball or a socket in accordance with the ball and socket configuration.

8. The transmission medium of claim 1 , wherein the plurality of rigid dielectric members each comprise barium titanate rods.

9. The transmission medium of claim 1 , wherein the plurality of rigid dielectric members each comprise rutile rods.

10. The transmission medium of claim 1 , wherein the dielectric cladding comprises a cellular plastic material for reducing an exposure of the guided electromagnetic waves to an environment that adversely affects propagation of the guided electromagnetic waves through the dielectric core and the cellular plastic material, and wherein the dielectric cladding is surrounded, at least in part, by an insulating jacket.

11. A coaxial cable, comprising:
a dielectric core comprising a plurality of opaque dielectric rods coupled together in a ball and socket configuration to propagate guided electromagnetic waves without a conductor; and
a dielectric cladding that surrounds at least a portion of the dielectric core.

12. The coaxial cable of claim 11 , wherein the dielectric core has a first dielectric constant that exceeds a second dielectric constant of the dielectric cladding.

13. The coaxial cable of claim 12 , wherein the first dielectric constant exceeding the second dielectric constant causes the guided electromagnetic waves to be bound to the dielectric core.

14. The coaxial cable of claim 11 , wherein the plurality of dielectric rods are arranged end to end in the ball and socket configuration.

15. The coaxial cable of claim 11 , wherein the plurality of dielectric rods are arranged in the ball and socket configuration to propagate the guided electromagnetic waves in a longitudinal sequence.

16. The coaxial cable of claim 15 , wherein the plurality of dielectric rods each includes a first end configured to mate with a previous one of the plurality of dielectric rods in the longitudinal sequence and a second end configured to mate with a next one of the plurality of dielectric rods in the longitudinal sequence.

17. The coaxial cable of claim 16 wherein each one of the first end and the second end are configured as one of: a ball or a socket in accordance with the ball and socket configuration.

18. The coaxial cable of claim 11 , wherein the plurality of dielectric rods comprise barium titanate or rutile.

19. The coaxial cable of claim 11 , wherein the dielectric cladding comprises a cellular plastic material for reducing an exposure of the guided electromagnetic waves to an environment that adversely affects propagation of the guided electromagnetic waves through the dielectric core and the cellular plastic material, and wherein the dielectric cladding is surrounded, at least in part, by an insulating jacket.

20. A method comprising:
receiving an electromagnetic wave; and
guiding the electromagnetic wave via a conductor-less transmission medium having a dielectric core comprising a plurality of rigid dielectric members configured in a ball and socket configuration to propagate the guided electromagnetic waves sequentially through the plurality of rigid dielectric members at non-optical frequencies.
