Tools for reformulating logical forms into zero-one mixed integer programs (MIPS) [PDF]

open access: yes, 1992
A systematic procedure for transforming a set of logical statements or logical conditions imposed on a model into an Integer Linear Programming (ILP) formulation or a Mixed Integer Programming (MIP) formulation is presented.

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Reformulations of mathematical programming problems as linear complementarity problems [PDF]

open access: yes, 1982
A family of complementarity problems are defined as extensions of the well known Linear Complementarity Problem (LCP). These are (i.) Second Linear Complementarity Problem (SLCP) which is an LCP extended by introducing further equality restrictions and ...

Ellipticity‐Controlled Exceptional Points and Cross‐Polarized Phase Singularities in Multi‐Layer Silicon Guided Mode Resonant Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.

Submicrosecond Electric Switching of Large Birefringence in the Isotropic Phase of Ferroelectric Nematics

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate ultra‐fast and efficient electro‐optical switching using the isotropic phase of ferroelectric nematic liquid crystals. A moderate electric field induces a transition to polar ferroelectric nematic order, producing large field‐induced birefringence with sub‐microsecond switch‐on and switch‐off times. This advance enables new opportunities

Mixed integer predictive control and shortest path reformulation [PDF]

open access: yes, 2010
Mixed integer predictive control deals with optimizing integer and real control variables over a receding horizon. The mixed integer nature of controls might be a cause of intractability for instances of larger dimensions. To tackle this little issue, we

A Trade‐Off between Pulse Energy and Stability in Seeded Free‐Electron Lasers

open access: yesAdvanced Photonics Research, EarlyView.
Seeded free‐electron lasers (FELs) require balancing competing factors for optimal performance. This work analyzes how dispersion strength influences output in high‐gain harmonic generation. Results reveal a trade‐off: maximizing pulse energy often comes at the cost of reduced stability and vice versa.
