PostMortem

Hi all I have a question regarding the Smith Chart. I have this exercise where it gives me the scattering parametres( not sure if that's what they are called in english) and i have to calculate the Γout, Γin etc. which i did, it also gives me the Q constant, so i have to put those on the Smith chart to get a circuit for that. My question is this: I know that after i draw the Q constant and place the Γout on the smith chart i have to connect those and work my way to the centre of the smith chart but how do i continue after the first line ? Do i choose the lines randomly or is there a certain way? Do i work only on the red lines or the blue lines? Or both? How do i choose which to use?

All of it. Of course i attempted to solve them but there are not similar exercises in my notes so i don't know how to solve them. I'm not looking for someone to solve them for me just maybe some formulas i can use or any help at all.

http://www.teiath.gr/userfiles/s.ath...im_2011_12.pdf I have some trouble in exercise 1 and 2. Exercise 1 says: There is a load q=-1μC in point A in axis x that is 0.15m form point O on the start of the axis. In the same time a second load Q is in point B of the axis Z that is 0.10m from point O on the start of the axis. The loads q and Q are moving with speeds u1 and u2. The direction of the two speed is shown on the graph, while we know that |u1|=10^7 m/s and |u2|=5*10^7 m/s. If the magnectic field on the point O is equal with zero calculate: a) The value and the sign for the load Q and b) The electric field on point O Exercise 2 says: Three loads Q1=-1nC, Q2=+2nC and Q3 are on axis x an specifically Q1 on the start of the axis, Q2 on the point X=0.1m and Q3 on the point X=0.3m The loads Q1 an Q2 are moving with speeds u1 and u2, while the load Q3 is not moving. |u1|=|u2|=10^8 m/s. If the total electric force that is being wielded on load Q1 equals zero calculate: A) The value and the sign for load Q3 B)The magnetic force on load Q1.
