说明：  Mie散射系数也叫米散射的Matlab计算程序。 当球形粒子的尺度与波长可比拟时，发生的散射为米散射。此时必须考虑散射粒子体内电荷的三维分布。此散射情况下，散射粒子应考虑为由许多聚集在一起的复杂分子构成，它们在入射电磁场的作用下,形成振荡的多极子,多极子辐射的电磁波相叠加，就构成散射波。又因为粒子尺度可与波长相比拟，所以入射波的相位在粒子上是不均匀的，造成了各子波在空间和时间上的相位差。在子波组合产生散射波的地方，将出现相位差造成的干涉。这些干涉取决于入射光的波长、粒子的大小、折射率及散射角。当粒子增大时，造成散射强度变化的干涉也增大。因此，散射光强与这些参数的关系,不象瑞利散射那样简单,而用复杂的级数表达，该级数的收□相当缓慢。这个关系首先由德国科学家G.米得出，故称这类散射为米散射。 (Mie Efficiencies)

说明：  The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
