Title:
コリメートされたコヒーレントな波頭を発生するためのミリメートル波トランスリフレクタおよびシステム
Document Type and Number:
Japanese Patent JP4746090
Kind Code:
B2
Abstract:
A planar multi-layer transreflector for generating collimated coherent energy comprises one or more of insulating layers between two or more metallic layers. The transreflector substantially reflects a cross-polarized component of an incident millimeter-wave signal and substantially transmits the remaining portions of the incident millimeter-wave signal. Each of the metallic layers comprises a plurality of rectangles arranged in a grid pattern radially varying in size within circumferential regions. The reflected cross-polarized component may be substantially orthogonal to the transmitted remaining portions. A substantially collimated and coherent wavefront comprising the remaining portions may be produced in a first direction, and substantially collimated and coherent wavefront comprising the cross-polarized components may be produced in a second direction.
