Thank you for the response and correction. Yep, I've made mistakes in G matrix (those typos have been made during writting matrices for this forum). I calculated ##\Delta_{1}## and ##\Delta_{2}## according to your suggestions: $$\Delta_{1} = \frac{Vs(R2+R3+R4)}{R2R3R4R5}$$
$$\Delta_{2} = -...
Hello,
I came up with a circuit that has two independent voltage-controlled current sources. I want to calculate voltage gain: ##G_{U} = \frac{U_{2}}{U_{1}}##. Moreover, I want to practice the nodal method at the same time. Below I'm sending schematic with marked nodes V1, V2, V3 and V4.

I've to model it as a two port network, even if I'm feeding only one port ? I'm just wondering how to solve this problem (how to calculate electric fields distribution) by using some method from EM field theory.
Ok, but how to derive relation between coupling/mutual capacitance/electric field between the lines and self-capacitance/electric field between middle line and ground plane ? How to start with it ? What I have to use ? Laplace, telegrapher's equation....????
You are right that, those lines can be treated as transmission lines. However, according to the theory, such a structures can be modeled by its self-capacitances (capacitances between conductors and ground plane), coupled by mutual capacitances. For calculations we can assume dielectric...
I prepared addition figure:
On the left we have case in which all coupled lines are in some relativelly large distance to each other. The electric field $$E_{2}$$ is existing in this case. However, if you decrease distance between the lines, the mutual electric fields are increasing what leads...
Yes.
Well, actually I'm not focusing on this case in terms of signal integrity,signal processing. Let we say that, I'm supplying obły the middle line (the "outside " lines - 1 and 3 are not polarized). My intuition and simulations are telling me that, the reduction of distance will change...
I'm considering AC in really high frequencies. I'm sending some figure in attachment. I'm trying to describe coupling between lines by using mutual capacitances between the lines.
Hello All,
I'm trying to create equation which can describe relation between electric fields of three coupled-lines and coupling between them. Let we say that, we have thee lines having infinit length which are placed above ground plane in distance h. The distance between coupled lines is...
Dear All,
I'm confused after reading of some chapter in a book, in which equations related to TEM mode have been derived. I want to prove mathematically, that Electric and Magnetic fields are ortogonal to each other. Thus, I use well known Maxwell equation:
$$\nabla \times \overrightarrow{E} +...
