  • Patent number: 8780439
    Abstract: Tunable plasmon resonant cavity arrays in paired parallel nanowire waveguides are presented. Resonances can be observed when the waveguide length is an odd multiple of quarter plasmon wavelengths, consistent with boundary conditions of node and antinode at the ends. Two nanowire waveguides can satisfy the dispersion relation of a planar metal-dielectric-metal waveguide of equivalent width equal to the square field average weighted gap. Confinement factors of over 103 are possible due to plasmon focusing in the inter-wire space.

  • Publication number: 20130124174
    Abstract: An internally parallel PDES (“IP-PDES”) system performs logical processes in parallel and further performs the internal processing of at least one logical process in parallel. Because the IP-PDES system is PDES-based, each logical process may have its processing performed in parallel with the other logical processes. The IP-PDES system allows for certain logical processes to be designated as internally parallel meaning that the logical process, referred to as an IP logical process, has its internal processing also performed in parallel. The IP-DES system allocates multiple nodes for such an IP logical process so that executable code of the IP logical process executes in parallel at the allocated nodes to simulate the occurrence of an event. Internal parallelism within a PDES may help overcome resource limitations and help speed up the overall simulation.
