1. A method of generating an RF field reflection, comprising:
positioning a planar grid in front of a conductive wall, the conductive wall highly reflective to incident electromagnetic energy, the grid comprising a set of linear spaced, parallel, electrically conductive lines; launching RF energy of an RF wavelength of interest at said grid and said conductive wall, wherein the launched microwave energy includes first and second energy components, said first and second energy components being linearly polarized components which are orthogonal to each other wherein said first component has a polarization direction parallel to the set of grid lines; reflecting at least a portion of said first polarization component of the incident energy from said grid and allowing the other of the components of the incident energy which is normal to the grid to pass through the grid with little reflection; reflecting the other of the components of the incident energy from the conductive wall, wherein the reflected first and second components of incident energy combine to form a standing wave pattern having a more uniform electric field than what would result without the grid. |
