RawDog (Rigorous Analysis of Wave Diffraction On Gratings) is a MATLAB application providing calculations for reflection and transmission coefficients (diffraction efficiencies) of periodic structures (such as optical gratings, photonic crystals, etc.) based on the Rigorous Coupled Wave Analysis (RCWA). RawDog is a completely free and open source application (in contrast, most commercial softwares cost thousands of euros) with additional features. Rigorous coupled wave analysis (RCWA) is an electromagnetic modelling tool for periodic boundary condition, such as, ID and 21) gratings. The method was invented by Moharam and Gaylord [ll. The RCWA for ID grating has proved to be very successful; there are a number of •Wave bending moments •Splitting Force calculations for Semi-Submersibles •Design and analysis of mooring systems •Time history of motions •Determination of Air Gaps •Calculation of Shielding Effects of ships and barriers •Multiple Body Interactions •Coupled mooring line-structure interaction •Cable Dynamics with intermediate ... Starting with a survey of wave propagation math methods, we delve into practical petroleum applications. Half of the book is devoted to drillstring vibrations, axial models with bit bounce and drill ahead, rock-bit interaction, stick-slip effects in torsional displacements, and coupled axial, torsional and lateral vibrations. Rigorous coupled-wave analysis (RCWA) and path-integral Monte Carlo (PIMC) codes can be obtained by contacting me(external link). Finally, discussion forums (support, suggestions, etc.) for some of these codes can be found here(external link). In this study, the mask 3D model we use is rigorous coupled-wave analysis (RCWA), which calculates the diffraction fields from a single plane wave incidence. A hybrid Hopkins-Abbe method with RCWA is used to calculate the EMF diffraction at a desired accuracy level while keeping the computation time practical.

PPML - RCWA is a project which implements the SM-RCWA, based on the formalisms of [a-d]. MELBOURNE, FL, February 23, 2016 – Modus Operandi, a company that delivers data discovery, integration, and Big Data analytics solutions for national security and commercial organizations, has been selected by the U.S. Office of Naval Research (ONR) to develop an activity-based intelligence system that will help spot unusual behavior by adversaries. The active amplifier adds 13 dB of gain to the antenna element. A two-element passive array utilizing electromagnetically coupled feeds was also designed, constructed tested. Finally, a rigorous full- wave analysis was made for a circular patch antenna electromagnetically fed with a microstrip line directly underneath the patch.
