Abstract

A method and fluid antenna apparatus are disclosed that incorporate optical agitation of electrolytes. The fluid antenna comprises a substantially enclosed container having a transparent window, an electrolytic fluid disposed within the substantially enclosed container, a light source, the light source producing an optical beam, wherein the light source is configured to direct the optical beam into the container; wherein the transparent window is configured to receive the optical beam from the light source; and wherein the beam has sufficient intensity to enable movement of charged particles in the electrolytic fluid in the container via radiation pressure.

First claim

We claim:

1. A fluid antenna, comprising:
an enclosed collapsible container having a transparent window, the enclosed collapsible container further having a single aperture configured to permit entry and exit of electrolytic fluid, wherein
the electrolytic fluid is disposed within the enclosed collapsible container;
a light source, the light source producing an optical beam, wherein the light source is configured to direct the optical beam into the enclosed collapsible container;
wherein the transparent window is configured to receive the optical beam from the light source; and
wherein an intensity of the optical beam is configured to enable movement of charged particles in the electrolytic fluid in the enclosed collapsible container via radiation pressure.

2. The fluid antenna of claim 1 , further comprising:
at least one reflective device configured to receive the optical beam from the light source, and to direct the optical beam into the enclosed collapsible container via the transparent window.

3. The fluid antenna of claim 1 , further comprising:
at least one focusing lens configured to receive the optical beam from the light source, and to direct the beam into the enclosed collapsible container via the transparent window.

4. The fluid antenna of claim 1 , further comprising:
at least one mirror configured to receive the optical beam from the light source; and
at least one focusing lens configured to receive the optical beam from the at least one mirror and to direct the optical beam into the enclosed collapsible container via the transparent window.

5. The fluid antenna of claim 1 , wherein the transparent window is mounted onto a surface and includes a water-tight O-ring seal.

6. The fluid antenna of claim 1 wherein the enclosed collapsible container is non-metallic.

7. The fluid antenna of claim 6 , wherein the enclosed collapsible container is a cone structure.

8. The fluid antenna of claim 1 , further comprising:
a current mast clamp that extracts signals from the fluid antenna.

9. The fluid antenna of claim 1 , wherein the light source produces a coherent monochromatic light beam.

10. A method for optical agitation of electrolytes in a fluid antenna, comprising the steps of:
providing an electrolytic fluid in an enclosed, conical, collapsible, non-metallic container, the enclosed, conical, collapsible, non-metallic container having a single aperture configured to permit entry and exit of the electrolytic fluid;
providing a light source that is configured to enable movement of charged particles in the electrolytic fluid via radiation pressure; and
directing an optical beam from the light source into the enclosed, conical, collapsible, non-metallic container having the electrolytic fluid, thereby causing movement of the charged particles in the electrolytic fluid via radiation pressure.

11. The method of claim 10 , wherein the directing step includes two sub-steps:
in a first sub-step, directing the optical beam from the light source to at least one mirror; and
in a second sub-step, directing the optical beam from the at least one mirror into the enclosed, conical, collapsible, non-metallic container.

12. The method of claim 10 , wherein the directing step includes two sub-steps:
in a first sub-step, directing the optical beam from the light source to at least one focusing lens; and
in a second sub-step, directing the optical beam from at least one focusing lens to the enclosed, conical, collapsible, non-metallic container.

13. A fluid antenna, comprising:
an enclosed, conical, non-metallic, collapsible container;
an electrolytic fluid disposed within the enclosed, conical, non-metallic, collapsible container, wherein the enclosed, conical, non-metallic, collapsible container has a single aperture configured to permit entry and exit of the electrolytic fluid;
a light source that produces an optical beam that is configured to enable movement of the electrolytic fluid in the enclosed, conical, non-metallic, collapsible container, thereby causing optical movement of charged particles in the electrolytic fluid via radiation pressure;
at least one mirror or focusing lens configured to receive the optical beam from the light source, and to direct the optical beam into the enclosed, conical, non-metallic, collapsible container via a transparent window; and
a current mast clamp that extracts signals from the fluid antenna.

14. The fluid antenna of claim 13 , wherein the light source produces an incoherent broadband light beam.

15. The fluid antenna of claim 14 , wherein the electrolytic fluid includes salt and water.

16. The fluid antenna of claim 15 , wherein the transparent window is mounted onto a ship deck.

17. The fluid antenna of claim 13 , wherein the electrolytic fluid includes silicon particulates in water.

18. The fluid antenna of claim 16 , wherein the window has a watertight seal to the mounting surface.
