摘要:
A metamaterial simultaneously exhibiting a relative effective permeability and a relative effective permittivity below unity over a wide bandwidth, including: one of a two-dimensional and a three-dimensional arrangement of unit cells, wherein each of the unit cells has a magnetic dipole moment and an electric dipole moment that are dependent upon one or more of an incident magnetic field and an incident electric field; and a coupling mechanism operable for coupling one or more of the incident magnetic field and the incident electric field to one or more devices. Optionally, the coupling mechanism includes one or more of a split ring and a pair of parallel plates coupled by one of a rod and a wire. The one or more devices are non-Foster elements.
摘要:
Embodiments of integrated device and associated methods of design are provided. Such embodiments include a metallic ground plane, dielectric material, ferrite puck and formed metal layer configured to define circulator and microwave device portions, or functions, within an integrated device unit. Impedance characteristics of each functional portion are determined independent of one another and are optimized with respect to each function. Respective matching network portions of each integrated device optimally couple the circulator portion with a microwave device portion and one or more connector ports. Integrated devices of the present teachings can be applied modularly at the systems level of communications, radar, and/or other contexts.
