Nanometer-scale patterning and individual current-controlled lithography using multiple scanning probes
(A I P Publishing LLC, 1999-06)
Scanning probe lithography (SPL) is capable of sub-30-nm-patterning resolution and
nanometer-scale alignment registration, suggesting it might provide a solution to the semiconductor
industry’s lithography challenges. ...
High Power CMUTs: design and experimental verification
(IEEE, 2012)
Capacitive micromachined ultrasonic transducers
(CMUTs) have great potential to compete with piezoelectric
transducers in high-power applications. As the output pressures
increase, nonlinearity of CMUT must be ...
Influence of missing array elements on phase aberration correction for medical ultrasound
(IEEE, 1994)
The influence of missing array elements on aberration correction based on time delay estimation using radio frequency signals of neighboring elements is experimentally investigated. Normalized cross correlation and sum of ...
Erratum to "Equivalent circuit-based analysis of CMUT cell dynamics in arrays" [May 13 1016-1024]
(IEEE, 2013-06-03)
In the original publication of the paper [1], the funding source was inadvertently omitted from the footnote on page 1016. The footnote should have read "Manuscript received November 20, 2012; accepted February 14, 2013. ...
Design of application specific processors for the cached FFT algorithm
(IEEE, 2006-05)
Orthogonal frequency division multiplexing (OFDM) is a data transmission technique which is used in wired and wireless digital communication systems. In this technique, fast Fourier transformation (FFT) and inverse FFT ...
Reflection coefficient null of acoustic waves at a liquid–anisotropic‐solid interface
(Acoustical Society of America, 1989-01)
he reflection coefficient of acoustic waves incident on a liquid–solid interface from the liquid side is numerically calculated for a general anisotropic solid oriented in any arbitrary direction. The reflection coefficient ...
Improvement of anisotropy sensitivity in the scanning acoustic microscope
(IEEE, 1989-03)
Thr response of the conventional scanning acoustic microscope (SAM) to anisotropic materials is theoretically investigated. For
this purpose, the reflection coefficient of plane acoustic naves incident
on a liquid-solid ...
Focusing surface waves using an axicon
(A I P Publishing, 1985-12)
Axicons are generators of waves which focus on a line. They are used in various imaging and nondestructive testing applications as bulk wave focusing devices with a very long depth of focus. In this letter, a new type of ...
Integration of through-wafer interconnects with a two-dimensional cantilever array
(Elsevier, 2000-05-22)
High-density through-wafer interconnects are incorporated in a two-dimensional (2D) micromachined cantilever array. The design addresses alignment and density issues associated with 2D arrays. Each cantilever has piezoresistive ...
A new directional acoustic lens: V-groove lens
(IEEE, 1993)
A new directional acoustic lens is introduced. The geometry is very similar to the line-focus lens except the lens cavity, which is shaped as a groove with flat-bottom V cross section. The slanted planar edges of the groove ...
