studying gaussian beam is a method to investigate laser beam propagation and abcd matrix is a fast and simple method to simulate gaussian beam propagation in different mediums. of the abcd matrices studied so far, reflection and refraction matrices at various surfaces have attracted a lot of researches. however in previous work the incident beam and the principle axis of surface are in parallel...

The requirements of a highly tilted sample and a well-polished surface for optimal EBSD pattern collection can make traditional SEM imaging challenging. With a tilted sample, SEM SE and BSE detectors are often in non-optimal positions for electron detection. For many materials, the polished surfaces produce weak contrast with SE imaging. Traditionally placed BSE detectors must be used with care...

Upon CO exposure to a Mo( 110) surface at 95 K, the initial ~0.3 monolayer (ML) of CO does not exhibit a vibrational frequency in the 1800-2200 cm-’ region, implying that the C-O axis is tilted with respect to the surface normal. Upon subsequent deposition of = 0.9 ML Cu at 95 Kfollowed by heating, infrared-reflection-adsorption-spectroscopy (IRAS) shows that a portion of the tilted CO molecule...

between measured CDAD spectra and calculated values for spatially oriented CO and NiCO clearly confirms the well-known perpendicular adsorption for CO on Ni(100), whereas for CO adsorbed on Fe(100) a tilted adsorption geometry was found. For NO/Ni(100) and for NO on the oxygenpreadsorbed Ni(100) surface, an average tilt angle of Q. =40+10' was observed. In the case of the oxygen-preadsorbed Ni(...

For a pendent drop whose contact line is circle of radius r0, we derive the Furmidge-like relation mgsin?=?2?r0(cos?min?cos?max) at first order in Bond number, where ?min and ?max are angles back (uphill) front (downhill), m mass ? surface tension liquid. The (or Eötvös) number taken as Bo=mg?(2r0?). tilt angle ? may increase from ?=0 (sessile drop) to ?=??2 (drop pinned on vertical wall) ?=? c...

This work details the design and simulation of an inconspicuous photonic paint that can be applied onto an object for anticounterfeit and tag, track, and locate (TTL) applications. The paint consists of three-dimensional metallic tilted woodpile photonic crystals embedded into a visible and infrared transparent polymer film, which can be applied to almost any surface. The tilted woodpile photon...
