So you mean that I should take each portion appart (where f(x) is constant) and calculate the integral. Then, I add them all together ?
Is there any other method where I can calculate Fourier series normally and then I multiply them by another factor which will make them increase or decrease ?
Hello, can we make a Fourier series expansion of a (increasing or decreasing) step function ? like the one that I attached here. I just want to know the idea of that if it is possible.
This is the refference to the article that I'm working with :
Huria, Tarun, Massimo Ceraolo, Javier Gazzarri, and Robyn Jackey. "High fidelity electrical model with thermal dependence for characterization and simulation of high power lithium battery cells." In Electric Vehicle Conference...
Thanks sir for your responce, but what I want to know why the term of spin-magnetic field interaction doesn't appear in the hamiltonian of the electron. is it because it is so small in front of the kinetic energy for example ?
Hi, in the case of free electrons gas under the effect of a magnetic field. The hamiltonian of an electron doesn't contain a term of Spin-Magnetic field interaction this means that it contains just the kinetic energy terms. Why is that ?
What do we mean by break points in band structure ? and what that sentence means : "if the band index were chosen in such a way that the energies are indexed in ascending order for any k then break points would appear in the εnk vs. k plot (with n fixed) wherever two lines intersect." ...
