Abstract In this work, a single degree of freedom resonant converter model is proposed and theoretical studies the are carried out. The suitable for waves with height up to 2 m period 5 seconds, such as on western coast Black Sea. It shown that at resonance its power increases significantly approaches values swell. high (up m) efficiency decreases, but remains relatively constant equal about ha...

A prohahilistic approach to design variables optimization of mechanical systems of multi ~ degrees of freedom is presented. The proposed method is based on the mathematical modelling of the systems, Optimization is understood as a calculation of the mean values and standard deviations of the random parameters chosen from the set of all design variables, which in the feasible domain minimize the...

Harnessing the full complexity of optical fields requires complete control all degrees freedom within a region space and time—an open goal for present-day spatial light modulators, active metasurfaces phased arrays. Here, we resolve this challenge with programmable photonic crystal cavity array enabled by four key advances: (1) near-unity vertical coupling to high-finesse microcavities through ...
