704257000

Abstract:

A human-machine communication method that includes the steps of receiving a first statement in a natural language from a user, generating first information based on the first statement and storing context information of at least one of the first statement and the first information. The method also includes the steps of optionally generating a question to be presented to the user in the natural language based on the context information, receiving a second statement in the natural language from the user and generating second information based on the second statement and the context information. A corresponding system is also provided.

Abstract:

A metasurface that is designed to control electromagnetic radiation (EMR) in ways that perform more than a single function. The metasurface has a substrate layer that has multiple asymmetric nanofeatures, each having a height (H) between λ/100 and 2λ. Each nanofeature has a particular length (D) that extends along a principal in-plane direction θ and a width (D) that is orthogonal thereto. Each nanofeature is tailored to scatter with different patterns one polarization state of electromagnetic radiation and one orthogonal polarization state of electromagnetic radiation.
