Pole-zero computation in microwave circuits using multipoint Padé approximation
(Institute of Electrical and Electronics Engineers, 1995-01)
A new method is proposed for dominant pole- zero (or pole-residue) analysis of large linear microwave circuits containing both lumped and distributed elements. The method is based on a multipoint Padé approximation. It ...
Increasing the sensitivity of the scanning acoustic microscope to anisotropy
(IEEE, 1987)
The response of the scanning acoustic microscope to anisotropic materials is theoretically investigated. For this purpose, the reflection coefficient of plane acoustic waves incident on a liquid-anisotropic-solid interface ...
Characterization and imaging with lamb wave lens at gigahertz frequencies
(IEEE, 1994-10-11)
Lamb wave lenses with conical refracting surfaces are fabricated for use at 400 MHz and 1 GHz. The conical surfaces are ground and polished with mechanical means and they are sufficiently smooth for the frequencies of ...
New high-resolution display device for holographic three-dimensional video: principles and simulations
(SPIE, 1994)
A new acousto-optical holographic display device, which is expected
to solve the display resolution and refresh problems that are common
to available holographic displays, is proposed. The device is based
on the ...
An efficient program for analysis of interconnect circuits
(Taylor & Francis, 1997)
A circuit simulation program using generalized asymptotic waveform evaluation techniques is introduced. The program analyses circuits with lumped and distributed components. It computes the moments at a few frequency points, ...
Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers
(IEEE, Piscataway, NJ, United States, 1998)
The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ...
Centimeter scale atomic force microscope imaging and lithography
(A I P Publishing LLC, 1998-09-21)
We present a 4 mm2 image taken with a parallel array of 10 cantilevers, an image spanning 6.4 mm taken with 32 cantilevers, and lithography over a 100 mm2 area using an array of 50 cantilevers. All of these results represent ...
An equivalent circuit for collapse operation mode of CMUTs
(IEEE, 2010)
Collapse mode of operation of the capacitive mi-cromachined ultrasonic transducers (CMUTs) was shown to be a very effective way for achieving high output pressures. However, no accurate model exists for understanding the ...
Reflection coefficient for a lossy liquid–lossless isotropic solid interface
(A I P Publishing, 1979-05)
A theoretical treatment of the reflection problem at a lossy liquid–lossless isotropic solid is given. The calculation results indicate that the reflection coefficient has a peak greater than unity. A physical explanation ...
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. ...
