    Abstract: A flexible printed circuit may be provided with an integrated heat and pressure spreading layer. The heat and pressure spreading layer may be configured to uniformly spread heat and pressure from a bonding tool across a portion of the flexible printed circuit during bonding of the flexible printed circuit to additional circuitry. During manufacturing of the flexible printed circuit, a sheet of heat and pressure spreading material may be attached to a sheet of flexible printed circuitry and the heat and pressure spreading material and the sheet of flexible printed circuitry may be die cut to form multiple flexible printed circuits each with a heat and pressure spreading layer. An electronic device may be provided with a flexible printed circuit with a heat and pressure spreading layer coupled to a component such as a display.

    Abstract: Terahertz metamaterials comprise a periodic array of resonator elements disposed on a dielectric substrate or thin membrane, wherein the resonator elements have a structure that provides a tunable magnetic permeability or a tunable electric permittivity for incident electromagnetic radiation at a frequency greater than about 100 GHz and the periodic array has a lattice constant that is smaller than the wavelength of the incident electromagnetic radiation. Microfabricated metamaterials exhibit lower losses and can be assembled into three-dimensional structures that enable full coupling of incident electromagnetic terahertz radiation in two or three orthogonal directions. Furthermore, polarization sensitive and insensitive metamaterials at terahertz frequencies can enable new devices and applications.
