Abstract

There is disclosed in one example an electromagnetic wave launcher apparatus, including: an interface to an electromagnetic waveguide; a first launcher configured to launch a high-frequency electromagnetic signal onto a first cross-sectional portion of the waveguide; and a second launcher configured to launch a lower-frequency electromagnetic signal onto a second cross-sectional portion of the waveguide.

First claim

What is claimed is:

1. An electromagnetic wave launcher apparatus, comprising:
an interface to an electromagnetic waveguide;
a first launcher configured to launch a millimeter-band electromagnetic signal onto a first cross-sectional portion of the electromagnetic waveguide; and
a second launcher configured to launch a lower-frequency electromagnetic signal onto a second cross-sectional portion of the electromagnetic waveguide.

2. The electromagnetic wave launcher apparatus of claim 1 , wherein the millimeter-band electromagnetic signal has a minimum frequency of approximately 200 gigahertz (GHz).

3. The electromagnetic wave launcher apparatus of claim 1 , wherein the millimeter-band electromagnetic signal has a frequency in the range of approximately 300 GHz to approximately 1 terahertz (THz).

4. The electromagnetic wave launcher apparatus of claim 1 , wherein the lower-frequency electromagnetic signal has a maximum frequency of approximately 200 GHz.

5. The electromagnetic wave launcher apparatus of claim 1 , wherein the lower-frequency electromagnetic signal has a maximum frequency of approximately 60 GHz.

6. The electromagnetic wave launcher apparatus of claim 1 , wherein the first cross-sectional portion is rectangular and has dimensions of less than 200 micrometers (μm)×400 μm.

7. The electromagnetic wave launcher apparatus of claim 1 , wherein the first cross-sectional portion is rectangular and has dimensions of less than 100 μm×400 μm.

8. The electromagnetic wave launcher apparatus of claim 1 , wherein the second cross-sectional portion is rectangular and has dimensions of approximately 1.5 millimeters (mm)×3 mm.

9. The electromagnetic wave launcher apparatus of claim 1 , wherein the second launcher is configured to launch the lower-frequency electromagnetic signal orthogonal to the millimeter-band electromagnetic signal.

10. The electromagnetic wave launcher apparatus of claim 1 , wherein the first launcher is a vertical launcher and the second launcher is a horizontal launcher.

11. The electromagnetic wave launcher apparatus of claim 1 , wherein one of the first and second launchers is a patch launcher, and wherein the other one of the first and second launchers is selected from the group consisting of a dipole launcher, tapered-slot launcher, or Vivaldi launcher.

12. The electromagnetic wave launcher apparatus of claim 1 , further comprising at least a third launcher.

13. A communication apparatus, comprising:
a mechanical interface to receive a dielectric waveguide;
a first launcher comprising circuitry and an interface to launch a first electromagnetic signal onto a first region of the dielectric waveguide, the first electromagnetic signal having a frequency in the range of approximately 300 GHz to 1 THz; and
a second launcher comprising circuitry and an interface to launch a second electromagnetic signal onto a second region of the dielectric waveguide, the second electromagnetic signal having a maximum frequency below 300 GHz.

14. The communication apparatus of claim 13 , wherein the second launcher is configured to launch the second electromagnetic signal orthogonal to the first electromagnetic signal.

15. The communication apparatus of claim 13 , wherein the first launcher is a vertical launcher and the second launcher is a horizontal launcher.

16. The communication apparatus of claim 13 , wherein one of the first and second launchers is a patch launcher, and wherein the other one of the first and second launchers is selected from the group consisting of a dipole launcher, tapered-slot launcher, or Vivaldi launcher.

17. The communication apparatus of claim 13 , wherein the maximum frequency of the second electromagnetic signal is approximately 200 GHz.

18. The communication apparatus of claim 13 , wherein the maximum frequency of the second electromagnetic signal is approximately 60 GHz.

19. A server rack, comprising:
a chassis;
a first server having a first launcher assembly, the first launcher assembly comprising a first launcher to launch a first high-frequency electromagnetic signal, and a second launcher to launch a second lower-frequency electromagnetic signal, wherein the first high-frequency electromagnetic signal is a millimeter-band signal;
a second server having a second launcher assembly, the second launcher assembly having a third launcher to launch a third high-frequency electromagnetic signal, and a fourth launcher to launch a fourth lower-frequency electromagnetic signal; and
a dielectric waveguide having a high-permittivity core waveguide disposed to communicatively couple the first launcher to the third launcher, and a lower-permittivity cladding disposed to communicatively couple the second launcher to the fourth launcher.

20. The server rack of claim 19 , wherein the core waveguide is not substantially concentric with the cladding.
