Abstract
Official abstract text for this publication.
An apparatus to modify an incident free space electromagnetic wave includes a block of an artificially structured material having an adjustable spatial distribution of electromagnetic parameters (e.g., ∈, μ, η, σ, and n). A controller applies control signals to dynamically adjust the spatial distribution of electromagnetic parameters in the material to introduce a time-varying path delay d(t) in the modified electromagnetic wave relative to the incident electromagnetic wave.)
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus, comprising: a stack of one or more layers having controllable reflective properties provided by metamaterial elements therein; and a controller configured to dynamically adjust the controllable reflective properties of the one or more layers to present an effective reflective surface at varying positions or orientations in the stack as a function of time to introduce a time-varying path delay d (t) in a reflected free space electromagne…
