High-Aspect Ratio Nanofabrication by Femtosecond Irradiation
2005 Pacific Rim Conference on Lasers & Electro-Optics, 2006We report on three-dimensional (3D) recording of the high-aspect ratio (far = 18) structures by holographic exposure using femtosecond pulses in a SU8 resist. Thickness of free standing planes was approximately 100 nm.

Experimental high precision profilometry of high aspect ratio samples
SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002Topographic features on the surface of samples can be imaged by using a wide variety of profilometry methods. Scanning Probe Microscopy (SPM) comprises a group of profilometry methods that are often used for high precision, nano-scale, short range 3-D imaging.

High Aspect Ratio Plasmonic Nanostructures for Sensing Applications
ACS Nano, 2011We present an experimental and theoretical study of plasmonic modes in high aspect ratio nanostructures in the visible wavelength region and demonstrate their high performance for sensing applications. Ordered and well-defined plasmonic structures with various cross-sectional profiles and heights are obtained using a top-down fabrication process.

Aeroacoustics of a High Aspect-Ratio Jet
9th AIAA/CEAS Aeroacoustics Conference and Exhibit, 2003Circulation control wings are a type of pneumatic high-lift device that have been extensively researched as to their aerodynamic benefits. However, there has been little research into the possible airframe noise reduction benefits of a circulation control wing.

Aspect Ratio Influence at High Subsonic Speeds
Journal of the Aeronautical Sciences, 1956The velocity induced by the thickness of a thin infinite wing in a parallel flow can be calculated, at some distance from the wing, by linearized subsonic compressible flow theory. If now, a portion of the infinite wing is removed from the flow, the velocity at any point on the wing will be less by the velocity induced by the portion of the wing which ...

Fabrication of high-aspect-ratio lightpipes
Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2011The authors report the development of two fabrication processes for creating high-aspect-ratio lightpipes in a 10 μm thick SiO2 layer, with smooth, uniform, and straight vertical sidewalls. Both processes require only standard optical lithography, without the need for advanced electron beam or deep-UV lithography.

High-Aspect-Ratio Structures for MEMS
MRS Bulletin, 2001Many microelectromechanical systems (MEMS) use the changing capacitance of movable parallel plates to drive and sense motion. An increase in this capacitance improves the performance of these micromechanical structures by means of increased electromechanical coupling for lower driving voltages and increased sensitivity of the micromechanical motion.

High Aspect Ratio Microstructures
2012The goal of this project is to find a substrate and parameters that allow the realisation of hight aspect ratio microstructures. We tried three substrates (Ti, Cr and Si), two photoresist thicknesses (50 and 100 [m]), two focalisation points (8 and 12 [m]), four laser powers (110, 88, 70 and 66 [mW]).
