Abstract: Methods of determining a material optical property for optical metrology of a structure is described. One method includes simulating a set of diffraction orders for a grating structure based on two or more azimuth angles and on one or more angles of incidence. A simulated spectrum is provided based on the set of diffraction orders. Another method includes simulating a set of diffraction orders for a grating structure based on two or more angles of incidence. A simulated spectrum is provided based on the set of diffraction orders.

Abstract: The invention disclosed is a massive multiplayer online game or event. An online server is connected to the world wide web. A first remote having a first sensor to detect movement and orientation of a first user, wherein first data signals are communicated from said sensor to the online server; and a second remote having a second sensor to detect movement and orientation of a second user, wherein data signals are communicated from said sensor to the online server are used. A machine readable program with the rules of a game or event thereon to coordinate the first data signals and the second data signals in accordance with the game.
