In this paper, we intend to study the synthesis of the multibeam arrays. The synthesis implementation’s method for this type of arrays permits to approach the appropriated radiance’s diagram. An adaptive particle swarm optimization algorithm (APSO) is proposed to synthesis multibeam antenna arrays. The problem is formulated and solved by means of the proposed algorithm. The examples are simulat...

Self-assembling DNA tiling lattices represent a versatile system for nanoscale construction. Self-assembled DNA arrays provide an excellent template for spatially positioning other molecules with increased relative precision and programmability. Here we report an experiment using a linear array of DNA triple crossover tiles to controllably template the self-assembly of single-layer or double-la...

In this paper, a novel approach is proposed for the calculation of ambiguous generator sets of directions for planar arrays. This approach is based on the concept of hyperhelical curves and their equivalent linear arrays, which provide a vehicle for investigating planar array ambiguities by adopting and extending techniques proposed for linear arrays. Thus, ambiguous generator sets of direction...

Despite their simple geometry, uniform linear arrays suffer from port-starboard ambiguity. Triplet arrays, where a set of three hydrophones is used inplace of a single omni-directional hydrophone, is one possible solution to the problem. An alternative is vector sensor arrays inwhich each hydrophone is replaced with acoustic vector sensor that measures both the acoustic pressure and particle ve...

In J. Phys. Soc. Jpn. 83, 034404 (2014), we designed a scheme of waveguide arrays with long-range linear coupling effects and studied the bright solitons in this system. In this paper, we further study the dynamics of dark and grey solitons in such waveguide arrays. The numerical simulations show that the stabilities of dark solitons and grey solitons depend on the normalized decay length and t...
