Array Factor for a Linear Array At this point, we’re able to predict the optimal time (or phase) delta between elements to achieve maximum antenna directivity. But we’d really like to understand and manipulate the complete antenna gain pattern. There are two main parts to this. First, th...

linear array sine function ratioaffine transformationsparallelogram array factorA closed-form expression is produced for the array factor of the electronically scanned, uniform-amplitude, finite-size hexagonal array. The underlying arguments depend upon a rotational symmetry cleavage of the hexagon into ...

Notice that the array factor will be maximum (=NI) when Ψ is zero or even multiples of π. This will determine the angle of the maximum radiation θmaxfor a given value of ϕ, or vice versa: (6.202)|AF(θ, ϕ)|max=I|sinNψmax2sinψmax2|=NI, ...
二度哈希较前面介绍的线性挖掘(Linear Probing)和二次挖掘(Quadratic Probing)提供了更好的避免冲突的策略。 Hashtable 类中包含一个私有成员变量 loadFactor,loadFactor 指定了哈希表中元素数量与位置(slot)数量之间的最大比例。例如:如果 loadFactor 等于 0.5,则说明哈希表中只有一半的空间存放了元素值,其余一半都为...
