通过用类似于阶跃折射率型光纤的理论，计算光子晶体光纤的基模模式折射率和色散。 (By analogy with the theory of step-index fibers, the effective index of the fundamental mode and the dispersion of PCF can be calculated. )

HI,i am ali shahbazy.how are you.

Traditionally an ac voltage regulator is made with a transformer tap changer or with an acac converter based on buck topologies, recently the developments in ac-ac converter makes feasible the implementation of voltage regulator with other topologies.
