J R. Kelly
… thin (0.5 mm to 0.75 mm) castings of palladium-, gold-, or nickel-based alloys. Metal substructures proved crucial to …

Accurate Gouy phase measurement in an astigmatic optical cavity

September 14, 2012
Author(s)
John R. Lawall, Mathieu Durand, Yicheng Wang
We present measurements of the Gouy phase accumulation for the fundamental mode of an astigmatic Fabry-Perot cavity over 70 % of its stability range. The method is based on simultaneous measurement of the resonant frequencies of the fundamental mode and

Comparing the Transient Response of a Resistive-Type Sensor With a Thin Film Thermocouple During the Post-Exposure Bake Process

April 1, 2004
Author(s)
Kenneth G. Kreider, D P. DeWitt, J B. Fowler, J E. Proctor, William A. Kimes, Dean C. Ripple, Benjamin K. Tsai
Recent studies on dynamic temperature profiling and lithographic performance modeling of the post-exposure bake (PEB) process have demonstrated that the rate of heating and cooling may have an important influence on resist lithographic response. Generally

Infrared Spectra of CICN + , CINC + , and BrCN + Trapped in Solid Neon

… the corresponding cation, ClCN+ or BrCN+. The NC-stretching fundamentals of the isocyanides trapped in solid neon lie … of ClCN+ to ClNC+ occurs. The two stretching vibrational fundamentals and several infrared and near infrared …

Location-specific Microstructure Characterization Within IN625 Additive Manufacturing Benchmark Test Artifacts

March 3, 2020
Author(s)
Mark R. Stoudt, Maureen E. Williams, Lyle E. Levine, Adam Abel Creuziger, Sandra A. Young, Jarred C. Heigel, Brandon Lane, Thien Q. Phan
Additive manufacturing (AM) of metals creates segregated microstructures with significant differences from those of traditional wrought alloys. Understanding how the local build conditions generate specific microstructures is essential for developing post

MODELING THE BURNING OF COMPLICATED OBJECTS USING LAGRANGIAN PARTICLES

July 4, 2010
Author(s)
Kevin B. McGrattan, Randall J. McDermott, William E. Mell, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka
A methodology is described for representing complicated objects within a computational fluid dynamics model. These objects are typically collections of similar items that are too small to define on the numerical grid that is used to solve the governing

Programmable Vector Point-Spread Function Engineering

April 1, 2006
Author(s)
M R. Beversluis, L Novotny, Stephan J. Stranick
We use a nematic liquid crystal spatial light modulator (SLM) to control the vector point spread function of a microscope objective by manipulating the pupil field polarization. In combination with an achromatic quarter-wave plate, the SLM acts as a
