Filed:

Mar 5, 2004

Appl. No.:

10/794491

Inventors:

Samual D. Tonomura - Rancho Palos Verdes CA, US
Terry C. Cisco - Glendale CA, US
Clinton O. Holter - Long Beach CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H05K009/00

US Classification:

174 35R, 174255, 174260, 257659, 257778

Abstract:

A hybrid assembly having improved cross talk characteristics includes a substrate having an upper surface. Conductive paths on the upper surface are provided for conducting high frequency signals. Regular polygons made of an electromagnetic band gap (EBG) material having slow wave characteristics are deposited on the upper surface and form a lattice for tessellating the upper surface. Each of the polygons has a periphery. The polygons are separated along their periphery from adjacent polygons by an interspace and are covered with an insulating material. Second polygons, also made of an electromagnetic band gap material, are deposited over the insulating material. Semiconductor structures are mounted over the second polygons. The semiconductor structures have a plurality of electrical contacts with the conductive paths. The regular polygons can be hexagons, triangles, octagons or any other combination that forms a lattice and can be printed onto the substrate.

International Classification:

G21C 1700

US Classification:

176 19R

Abstract:

A multi-sensor radiation detection system for removable insertion into a nuclear reactor wherein one conductor of all the sensors is a single, common element. This single common element is contained within a tubular metallic sheath and in cross-section comprises a multiple radial armed metallic conductor having a star shaped cross-section dimensioned to form wedge-shaped compartments throughout the active radiation detecting length of the metallic sheath.
