Abstract: An article having low wettability is presented. The article comprises a body portion and a surface portion disposed on the body portion. The surface portion comprises a plurality of features disposed on the body portion, and the features have a size, shape, and orientation selected such that the surface portion has a wettability sufficient to generate, with a reference liquid, a contact angle of at least about 100 degrees. The features comprise a height dimension (h) and a width dimension (a), and are disposed in a spaced-apart relationship characterized by a spacing dimension (b). The ratio of b/a and the ratio of h/a are such that the drop exhibits metastable non- Wenzel behavior.

Abstract: An ohmic RF MEMS relay includes a substrate with a capacitive coupling, Csub; two actuating elements electrically coupled in series, so as to define a channel, wherein the actuating elements are configured to be independently actuated or simultaneously operated. The actuating elements have their own capacitive coupling, Cgap; a midpoint on the channel is in electrical communication with the actuating elements; and an anchor mechanically coupled to the substrate and supporting at least one of the actuating elements. Also, an ohmic RF MEMS relay that includes an input port; a plurality of first MEMS switches that make up a first switching group in electrical communication with the input port, thereby defining a plurality of channels each leading from each of the MEMS switches; and at least one outlet port along each of the channels distal from the first switching group and in electrical communication with the input port.

Abstract: A method of manufacturing a layered material stack that includes a plasmonic interface between a plasmonic material and optical waveguide material is disclosed. The method includes providing a substrate layer, disposing a layer of plasmonic material on the substrate layer, depositing a metal constituent of an optical waveguide material directly onto the layer of plasmonic material, and anodizing the metal constituent of the optical waveguide material to form an optically transparent oxide of the metal constituent configured to couple light into the layer of plasmonic material, with the optically transparent oxide of the metal constituent forming an optical waveguide structure.

Abstract: An electrical through-connection, or via, that passes through a substrate (2 2) to a bus (28) on a first surface (21) of the substrate (22). The via may be configured with an interlock (46) such that the electrically conductive core (60) of th e via is constrained to thermally expand towards the second surface (23), away from t he bus (28), thus preventing damage to the bus (28). The interlock (46) may be a local constriction or enlargement of the via near the first surface (21) of the substrate (22). The via may be greater in length along the bus (28) than a unit spacing of beams (30) in a parallel microswitch array (20) actuated in unison along the bus (28). The via may be narrower in width than in length, and may form a trapezoidal geometry that is larger at the second surface (23) of the substrate (22) than at the first surface (21).

Abstract: Multiple microelectromechanical systems (MEMS) on a substrate (20) are capped with a cover (28) using a layer that may function as a bonding agent, separation layer, and hermetic seal. A substrate (20) has a first side (20A) with multiple MEMS devices. A cover (28) is formed with through-holes (40) for vi as (40), and with standoff posts (34) for layer registration and separation. An adhesive sheet (42) is patterned with cutouts (44) for the MEMS devices, vias (40), a nd standoff posts (34). The adhesive sheet (42) is tacked to the cover (28), th en placed on the mems substrate (20) and heated to bond the layers. The via holes (40) may be metalized with leads for circuit board (58) connection. The mems units (22) may be diced from the substrate (20) after sealing, thus protecting them from contaminants.
