Abstract: An antenna array with a layered structure having a base layer with a metamaterial structure, a printed circuit board (PCB) layers, a feed layer arranged on the opposite side of the PCB from the RF IC(s), and a radiating layer arranged on the feed layer. The radiating layer having a plurality of radiating elements. The metamaterial structure is arranged to attenuate electromagnetic radiation propagating between the at least two adjacent waveguides in the frequency band.

Abstract: An antenna array with a layered structure comprising a base layer with a metamaterial structure; a printed circuit board (PCB) layer; a feed layer arranged on the opposite side of the PCB from the RF IC(s); and a radiating layer arranged on the feed layer comprising a plurality of radiating elements, wherein the metamaterial structure is arranged to attenuate electromagnetic radiation propagating between the at least two adjacent waveguides in the frequency band.

Abstract: A microwave device is based on gap waveguide technology, and comprises two conducting layers (101, 102) arranged with a gap there between, and protruding elements (103, 104) arranged in a periodically or quasi-periodically pattern and fixedly connected to at least one of said conducting layers, thereby forming a texture to stop wave propagation in a frequency band of operation in other directions than along intended waveguiding paths. Sets of complementary protruding elements are either each formed in said pattern and arranged in alignment and overlying each other, the complementary protruding elements of each set forming part of the full length of each protruding element of the pattern, or the sets of complementary protruding elements are arranged in an offset complementary arrangement, the protruding elements of one set thereby being arranged in between the protruding elements of the other set.

Abstract: This invention relates to a novel group 2, 3 or 4 transition metal metallocene catalyst compound that is asymmetric having two non-identical indenyl ligands with substitution at R2 having a branched or unbranched C1-C20 alkyl group substituted with a cyclic group or a cyclic group, R8 is an alkyl group and R4 and R10 are substituted phenyl groups.

Abstract: An expandable and collapsible cabinet contains a body being an elongated plate and including plural board portions and a plurality of bending portions; each bending portion integrally connecting with and between two abutting board portions, and between the each bending portion and each board portion is defined a grooved area to provide a collapsible space; a bottom cover; a top cover; when the body is folded into a rectangular frame by folding four grooved areas 90 degrees, the bottom cover and the top cover are covered on a bottom end and a top end of the body.

Abstract: A method for establishing a control response between a portable control device and a controlled device is provided. The portable control device includes a touch interface for receiving control instructions. The control instructions may be issued from a user, who does not have to keep his eyes on the portable control device during control. In an embodiment, the method is applied to a portable control device to remotely control a connected TV, which may include a preview function, so that the user can control the connected TV without keeping his eyes on the portable control device. Response from a preview window on the TV can guide the user to correctly issue his control instructions from the portable control device. The control instructions can be issued by, for example, contacting the touch interface or sliding the touch interface.
