I read from various literature that a short circuited quarter wave stub is open for AC and short for DC.
Can somebody explain the reason behind this?

Hi my friend!
we can draw an equivalent circuit for The quarter wave stub , it is a complex filter . and each filter has an impedance , this impedance , is not real , thus for DC , we have , not impedance , (short circuit) , and for AC we have complex impedance . for more information , refer to the Secrets of RF circuit design of joseph j carr ( incredible book at this area and simple)

Thank you so much Goldsmith.
Appreciate it so much.
