It is concluded that when a small solid angles range adjacent to the main direction in the far field is considered, the parallel beams combining of compact antenna arrays has its priority if the phases can be controlled, and the parallel beams combining of sparse antenna arrays has its priority if the phases can not be controlled.

Further oxidation treatment or reduction treatment of molybdenum dioxide nanowire arrays resulted in molybdenum trioxide nanowire arrays and molybdenum nanowire arrays. We fabricated WO3 nanowire arrays successfully by further oxidizing W18O49 nanowire arrays. Based on the vertical aligned zinc oxide nanowire arrays, we prepared the aligned zinc oxide/silicon core-shell nanowire arrays, zinc oxide nanowire-zinc silicate nanotube heterojunction arrays and zinc silicate nanotube arrays by adjusting the size of the templates as well as the annealing temperature.

BCBBs are designed for not only symmetric linear arrays but also asymmetric linear arrays, are arrays and circle arrays. The BCBBs designed are tested by LFM signals, and the results show that the BCBBs achieve good quality. The word length of the filter efficients are studied from the view of engineering implementation. It is shown that using 8 bits can satisfy the requirement. Multi-beam BCBBs with 2 degree beamwidth in two octave and 1/3 octave frequency band are designed and tested for a specified array.

In the device fabrication, first by the low implantation on the top of the device the isolation between elements in arrays is achieved, and then the deep implantation on the upper layer down to the active layer can provide the transverse current confinements in individual elements in arrays. At the same time the thermal interaction between elements in arrays has also been studied.
