An important problem associated with multiple pixel liquid crystal (LC) modulators is the incidental diffraction due to amplitude and phase gratings formed by the improperly modulated regions between electrodes. This problem becomes more of an issue as the resolution of the SLM increases and the size of the pixels begins to approach the size of the inter-pixel spacing. We perform 2D director pr...

Polymer-dispersed liquid crystals (PDLCs) represent an important new class of materials for optical device applications. Their valuable advantages such as low operating voltage, high contrast ratio, requiring no extra optical elements (i.e. polarizer), quick electrooptical response, no leakage of materials, simple fabrication, low-cost production and ease of processing make them more popular ov...

A system of two liquid-crystalline phenylpyrimidines differing strongly in molecular length was studied. The phase diagram of these two chemically similar mesogens, with a length ratio of 2, was investigated, and detailed X-ray diffraction and electrooptical measurements were performed. The phase diagram revealed a destabilization of the nematic phase, which is present in the pure short compoun...

In this paper biophysical bases and frontiers of the acupuncture-based complementary medicine are considered, and essential significance of its resonance microwave (MW)/ultralowfrequency (ULF) electromagnetic (EM)/ionic nature as well as the quantum-holographic "electrooptical" neural-network-like-function of the acupuncture system are pointed out, as supported by microwave resonance therapy (M...

This paper presents a parametric analysis of the sense and avoid capability for an electrooptical system on unmanned aircraft. Our sensor analysis is based on simulated encounters from a new U.S. airspace encounter model that provides a comprehensive distribution of typical visual flight rule (VFR) aircraft behavior and encounter geometries. We assess the exchange between the sensor field-of-vi...
