What about the TE10mode? TE 1, 010 mn 22 c,10 11 0 1 22 f aba CAUTION: We cannot yet say that the TE10is the fundamental mode because we have not checked the cutoff frequency of the TM modes. Since a > b, we conclude that the first‐order mode is TE10because it has the lowest cutoff frequency.

the Drude theory of conductors. This is a simple classical model, and many of its concepts extend to the quantum case. A more careful account of the Drude model can be found in the first chapter of “Solid State Physics” by Ashcroft and Mermin. The Drude model envisions a conductor as a gas of free current-carrying charges.

Drude used giving This is the Lorentz number. The above relation is called Wiedemann-Franz law and is obeyed quite well by Alkali metals over a narrow temperature range. Drude was lucky – he overestimated the electronic specific heat by 100 times (electronic C v at room temperature is nowhere close to

Lecture Notes on Solid State Physics - Kevin Zhou

The Drude theory of metals, introduced in 1900, models a metal as a classical gas of electrons, assumed to be the valence electrons of the atoms used to form the metal. • We assume the electrons don’t interact with each other at all, the ‘independent electron ap-proximation’. However, we will allow collisions with the lattice ions.

Drude model: the simplest treatment of the electrical conductivity. Four major assumptions: 1. Electrons are treated as classical particles within a free-electron approximation: neglect the interactions with other electrons and ions; no external electromagnetic fields - move uniformly in a straight line. In the
