Generalized inverse lithography methods for phase-shifting mask design
Optics Express, 2007 Optical proximity correction (OPC) and phase shifting masks (PSM) are resolution enhancement techniques (RET) used extensively in the semiconductor industry to improve the resolution and pattern fidelity of optical lithography. In this paper, we develop generalized gradient-based RET optimization methods to solve for the inverse lithography problem ...

An inverse method to fast-track the calculation of phase diagrams for sonoluminescing bubbles
Ultrasonics Sonochemistry, 2021 A sound driven air bubble can be transformed into an argon bubble emitting light pulses stably. The very foundation to investigate the sonoluminescing bubble is to accurately determine the ambient radius and gas composition in the interior. The conventional approach is to model the air-to-argon transformation process through a large number of bubble ...

Probing of the topological phase transition in a disordered 1D acoustic system
AIP Advances, 2022 The methods to determine the Zak phase introduced by previous studies are usually limited to the periodic systems protected by the inversion symmetry. In this work, we build a one-dimensional chiral symmetric acoustic chain with controllable disorder to ...

One-phase inverse stefan problem solved by adomian decomposition method
Computers & Mathematics with Applications, 2006 The Adomian decomposition method is nicely applied for obtaining a formal solution to the inverse Stefan problem. However, there is no guarantee of the convergence as \(n\) or \(m\) increases. Moreover, the method is restricted to exact data.

A new perspective on stable inversion of non-minimum phase nonlinear systems [PDF]
Modeling, Identification and Control, 2008 We present a new perspective on the problem of stable inversion of nonlinear non-minimum phase systems. It is based on the notion of convergent systems. The machinery of convergent systems allows us to obtain novel qualitative and quantitative conditions
