The Potential Of Optical Lithography

SPIE Proceedings, 1985
The limits of submicron patterning by optical lithography were estimated by computer simulation. As a result, the optimum numerical aperture, NA, which gives the highest resolution was determined. Assuming that the permitted defocus value is +1 pm, the lithographic resolution of about 0.7 pm was obtained with NA 0.5 and near-UV exposure.

Phenomenological optical potentials

The European Physical Journal Plus, 2018
In this paper a “pedagogical” description of the scattering of two colliding nuclei is given. Some essential concepts are introduced, like the cross-section definition and the basic ingredients of scattering theory, which are preparatory for the discussion on the optical model. Phenomenological optical potentials are described, like the Woods-Saxon and

On the theory of the optical potential

Nuclear Physics, 1962
Abstract Nucleon scattering on nuclear density fluctuations inside the nucleus is considered. The scattering coeffecient determining the imaginary part of the optical potential is expressed through the nucleon-nucleon scattering amplitude and the spectral distribution of the space-time correlation function of nuclear density fluctuations.

Potential Of Optical Lithography

Optical Engineering, 1987
Practical resolution limits of submicrometer patterning by optical lithography are estimated by computer simulation. As a result, the optimum numerical aperture NA that gives the highest resolution is determined. Assuming that the permitted defocus value is ± 1 µm, a litho-graphic resolution of about 0.7 µm is obtained with 0.5 NA and near-UV exposure.

Optical potential for the deuteron

Nuclear Physics A, 1968
Abstract The optical potential of the deuteron is expressed in terms of neutron and proton optical potentials using the operator formalism of Feshbach. A fairly good description of the real and imaginary parts of the deuteron optical potential is obtained only when a few correction terms are taken into account.

Optical Imaging of Cardiac Action Potential

2015
This chapter reviews the major milestones and scientific achievements facilitated by optical imaging of the action potential in the heart over more than four decades since its introduction. We discuss the limitations of this technique, which sometimes are not fully recognized; the unresolved issues, such as motion artifacts, and the newest developments
