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 of transmissive materials; and a controller coupled to the stack, wherein the one or more layers have controllable metamaterial elements therein providing controllable indices of refraction, and wherein the controller is configured to dynamically adjust the controllable indices of refraction of the one or more layers to at least partially transmit an incident free space electromagnetic wave…
