microstrip right angle bends
Hi
I want to calculate L and C in equivalent circuit of a 90 degree microstrip bend. it is not important to calculate them in finite element , finite difference and so on.
is there any one has a code about it or help me how to calculate them.
I know one way. I write a 3D FDTD with PML code (sulivan code) and I simulated a microstrip in it.I should exert a voltage in one of ports and read current in the other port. after it I should use FFT to transform the to frequency domain. by dividing V and I, I will calculate Z or Y.
in order to do it I have some problems:
1-how should I simulate feed? when I use dz(x,y,z)=pulse in a input of microstrip , at that point I have radiation to all directions. is it correct?
2-how should I simulate match load at the other port to absorb the current?
3-I should use j=H×n or I=∫H.dl to calculate current?
best regards
