**sgcpw**

hi to all,

i need to find characteristics impedance of the stacked grounded coplanar waveguide with out using any numerical simaultion.

is there any analytical formuals available for that......

if i use fdtd simlation tool, wat r the possible parameters available for stacked grounded coplanar waveguide to extract?

and what is the procedure that i need to follow to extract those parameters.

if i use pml boundary conditions for sgcpw , what r the locations i hav to apply pml cells .

plz help me........

waiting for somones help........
