Shunt capacitance in the transmission line causes voltage amplification ( Ferranti effect ).
2.
It adversely affects the time needed to turn off the diode and its shunt capacitance.
3.
The shape of the diffusion-like pattern is caused by the effect of the shunt capacitance.
4.
NBOC is the Network Build Out Capacitor, which is set to the avergae shunt capacitance through the telephone central office switch.
5.
Implementing a true open circuit in planar technology is not feasible because of the dielectric effect of the substrate which will always ensure that the equivalent circuit contains a shunt capacitance.
6.
Now the only thing left to do is to find the lowpass FSS that yields the shunt capacitance values called out in Fig . 2.3 . 1-4.
7.
The percentage mitre is 100x / d To a first approximation, an abrupt un-mitred bend behaves as a shunt capacitance placed between the ground plane and the bend in the strip.
8.
Because DSL operates above the 3.4 kHz voice limit, it cannot pass through a load coil, which is an inductive coil that is designed to counteract loss caused by shunt capacitance ( capacitance between the two wires of the twisted pair ).
9.
Fitting a shunt capacitor to a real FSS is done by repeated running of a first principles code to match the reflection response of the shunt capacitor with the reflection from a capacitive FSS . Patch-type FSS below resonance will produce a capacitive shunt admittance equivalent circuit, with closer packing of elements in the FSS sheet yielding higher shunt capacitance values in the equivalent circuit.
