To simulate the interaction of buried defects and absorber features in EUV masks, a full three-dimensional, fast, integrated, simulator based on ray tracing and a thin mask model is presented. This simulator allows rapid assessment of the effects of buried defects on EUV printing. This new simulator, RADICAL (Rapid Absorber Defect Interaction Computation for Advanced Lithography), gives a 450X ...
To simulate the interaction of buried defects and absorber features in EUV masks and their effects on projection printing, a prototype 2D, fast, integrated, simulator based on ray tracing and a thin mask model is presented. RADICAL (Rapid Absorber Defect Interaction Computation for Advanced Lithography), consists of three sequential steps: the propagation of the mask illumination down through t...
A model-free algorithm is developed for the reactive control of a wave energy converter. Artificial neural networks are used to map the significant wave height, wave energy period, and the power take-off damping and stiffness coefficients to the mean absorbed power and maximum displacement. These values are computed during a time horizon spanning multiple wave cycles, with data being collected ...
A key component in bringing ocean wave energy converters from concept to commercialization is the building and testing of scaled prototypes to provide model validation. A one quarter scale prototype of an autonomous two body heaving point absorber was modeled, built, and tested for this work. Wave tank testing results are compared with two hydrodynamic and system models—implemented in both ANSY...
In this article, a planar multilayered structure is considered as a radar absorber for normal and oblique incidence plane wave. We used actual dispersive material which could be used as a metamaterial for our structure. The formulation can respond any arbitrary polarization i.e. TE or TM. The optimizations are done in a wide frequency band and at a wide range of incident angles that has reached...
Research toward the development of point absorber ocean wave energy converters (WEC) is migrating from energy absorption of ocean wave heave only, to the absorption of heave and surge. Due to the additional dimension of surge, the mathematic relationship between the ocean waves and the WEC has shifted from a linear model to a nonlinear model. This change has made back driven wave height from de...
We report on the fast (approximately 50 micros) remote-controlled switching between continuous-wave (cw), cw mode-locked (ML) and Q-switched ML modes of operation of a Nd:YVO(4) laser using an optically-pumped saturable absorber (SA). Pulses as short as 40 ps with an average output power of 0.5 W are obtained in cw ML regime.
