Patent ID: 7356791

Claim:
An apparatus for performing an electromagnetic analysis of an electrical circuit structure, comprising: at least one software module; configured for inputting a representation of an electrical circuit structure; and for defining at least a pair of distinct super-sections within said electrical circuit structure, each one of said distinct super-sections having a perimeter, said distinct super-sections include a first super-section and a second super-section that each include a first common location that is located within both said first super-section and said second super-section, and where said first super-section includes a first common port that is located at said first common location and includes a first uncommon port that is located at a first uncommon location, said first uncommon location is not located within said second super-section, and where said second super-section includes a second common port that is located at said first common location and includes a second uncommon port that is located at a second uncommon location, said second uncommon location is not located within said first super-section; and said software module configured for determining an electro-magnetic coupling between said first port by performing actions including a first electro-magnetic analysis of said first super-section, by performing a second electro-magnetic analysis of said second super-section and by combining the results of said first electro-magnetic analysis and said second electro-magnetic analysis to yield a combined result.
