Thank you for your answer. I was thinking about something along the same line.
The logic indeed works if we consider an electric dipole under a constant electric field.
Assuming that one of the charges is in a fixed position, if we don't consider any damping force, the system starts to oscillate...
Thank you for your reply first of all.
My doubt comes from the fact that when the impedance formula is obtained from Maxwell's equations in the phasor/fourier domain for a plane wave solution, ω=0 is a possible frequency.
A sinusoid with zero frequency exists, it's a constant value. A plane wave...
For a plane wave traveling in free space we know from Maxwell's equations that:
Z= E/H=√μ0/ε0 = 377Ω
The meaning of the wave impedance is that if we have an electric field oscillating with amplitude E0 in a medium (in this case the vacuum) a magnetic field will be induced with amplitude E0/Z...
Yes.
But ro(x,y,z) or sigma(x,y,z) is not constant because you have a single material.
But because we assume the material is homogeneous hence has a perfect structure with no fluctuations of parameters in space.
You should study the classical theory of conduction and the Drude model first.
Trust me that you can't understand electronics if you don't get this elementary physics, things are going to get much much more complex once you study transistors.
Btw to sum it up.
For electrons J = -n*e*vd
where...
I have a question about Thomson scattering from an electron hit by an incident em plane wave.
The derivations that I have found all state the same thing.
You have an electron in the origin at rest as the initial condition, the incident plane wave is linearly polarized towards z with amplitude...
A wave is the propagation of a perturbation, in this case an electromagnetic field.
If you have a source emitting a sinusoidal wave at a certain frequency ω it means that, at the source, in a time T=2π/ω the field has completed a full oscillation.
When at the source the field has completed a...
Thank you for your reply.
I was considering the ideal case with R=0.
But you gave me the right hint and I think that I get it now.
Impedance at ω=0 (ideal costant signal of infinite duration) is infinite and gives me a DC component on the capacitor.
The transient in this case doesn't go to zero...
Hi, I have a question about LC series oscillators. Specifically when a DC supply is applied.
Solving the differential equation for such circuit using as initial conditions at t=0 that Vc=0 and I=0 I get as a solution that the circuit oscillates and the voltage across the capacitor has an...
