Abstract

A wave generating device including a reflective surface adapted to reflect energy waves to a focus, and an energy wave transducer positioned at least partially around and outwards from the reflective surface, and adapted to generate an energy wave inwards towards the reflective surface through a wave propagating medium disposed between the reflective surface and the energy wave transducer.

Claims

1. A wave generating device comprising:

a reflective surface adapted to directly reflect energy waves to a focus, said reflective surface being formed by a shape revolved about an axis of revolution, wherein said focus is located on said axis of revolution; and

an energy wave transducer positioned at least partially around said reflective surface and radially outwards from the axis of revolution of said reflective surface, and adapted to generate an energy wave radially inwards towards said reflective surface through a wave propagating medium disposed between said reflective surface and said energy wave transducer.

2. The wave generating device according to claim 1, wherein said energy wave transducer is formed by a shape revolved about said axis of revolution.

3. The wave generating device according to claim 1, wherein said reflective surface is parabolic.

4. The wave generating device according to claim 1, wherein said energy wave transducer is cylindrical.

5. The wave generating device according to claim 1, wherein said energy wave transducer is conical.

6. The wave generating device according to claim 1, wherein said energy wave transducer comprises an electromagnetic element mounted on a support, said electromagnetic element adapted to alternatively and repeatedly push and repel a repulsive member to produce inwardly propagating energy waves through said wave propagating medium.

7. The wave generating device according to claim 1, wherein said reflective surface has an aperture formed therein pointed towards said focus.

8. The wave generating device according to claim 1, further comprising an imaging device disposed in said aperture.

9. The wave generating device according to claim 1, further comprising an energy source disposed in said aperture.

10. The wave generating device according to claim 1, wherein said energy wave transducer is positioned completely around said reflective surface.
