Micro-forging technique for rapid, low-cost manufacture of lens array molds and its application in a biomedical instrument
… Using this process, molds were fabricated for rectangular arrays of 1-10,000 lenses with apertures of 0.25-1.6 mm, sag heights of 3-130 [mu]m, inter-lens spacings of 0.25-2 mm, and fill factors of 0-100%. Mold profiles have roughness and figure error of 68 nm and 354 nm, respectively, for 100% …

Optimal configuration of large arrays of floating bodies for ocean wave energy extraction
… approach to energy harvesting is to use arrays of oscillating bodies. The advantage of such a solution lies in potential amplification of the wave field through the interactions of waves that are diffracted and radiated by the bodies. Recent examples from other fields of physics (e.g. …

Synthesis of Ultra-Wideband Array Antennas
… Factors contributing to bandwidth limitation of arrays include array factor, radiation characteristics of the array element, and inter-element mutual coupling. Strictly speaking, distortion-free transmission or reception of ultra-wideband signals can be maintained if the magnitude of the radiated …

Analysis and Synthesis of a New Class of Low Side Lobe Planar Arrays
Numerical techniques for designing planar arrays with low side lobe level often require memory intensive optimization algorithms and also initialization in the form of some known values of radiation pattern parameters beforehand - information that may not be available when designing arrays. A few …

Novel Methods for Recording and Analysing High-Density EMG Signals of the Hand & Forearm
… More recently, high-resolution multi-electrode arrays have expanded to the field of EMG, a technique named high-density electromyography (HD-EMG). This technique retains the beneficial aspects of sEMG while increasing the resolution of the collected data, which can provide an improved …
