In eliptical polarization there is a phase difference of n*∏/2 and the amplitudes of the components are different.

Dear friends i know that a wave is linearly polarized if its components have a phase difference of n*∏ and is circularly polarized if phase difference is n*∏/2. But what if phase difference is neither ∏ nor ∏/2? like for E= ax exp(-j(βy-∏/4)) + azexp(-j(βy-∏/2))... thanks in advance...

thanks vk6kro and yungman.

Hi I have taken a very rudimentary course on antenna theory, now i am interested in further deepening my knowledge. I have bought myself Balanis's book on antenna theory, I need some guidance regarding what chapters should i study as it is quite a large book. Secondly, after i have got...

aaahhh! took so much of my time. n=10^10, p=10^10, n_i^2=10^20. dope it 10^18 and doing so will cause recombination so let's approx 10^8 holes recombine with electrons then n=(10^2 +10^18) ≈ 10^18 and p=10^2. then np= (10^18)*(10^2)= n_i^2. I hope i am right now?

for the sake of understanding and as an example let them be just 'n0 carriers per cubic cm'

Suppose in intrinsic silicon, n0=100 then p0=100 and carrier concentration will be 10,000. Now I add 1000 pentavalent impurity atoms. then intuitively n0=1100 and p0=100 or if some or all of the holes are filled by electrons then n0=1000 and p0=0. This is what i want things to be... Can't figure...

Hello Friends I am having trouble understanding law of mass action for extrinsic semiconductors. How the carrier concentration remain the same after the addition of impurities. I want to know conceptually not mathematically.
