Calculate the non-trivial solution using matrix equation in (a) as Ces (ka) = cos (kb) cos[k, (a-b)]- Apply following Express to obtain V.; Vb = Constant b = Constant, tb-so kb-so, sin (kb) kb and cas (kb) 1 cos(ka) = Cos (ka) - sin (kb) sin(k.la-b)] 21,4 approximations (delta function) (e) Select Some value mvoba Repeat (b) and Corresponding expressions. (C) of E for sin (ka) k, a E <0 to and estimate the band gaps. obtain the Consider E(K) = + (1 - Cos (kl)] where E is the energy band width. Find the group velocity and affective particle mass. An electromagnetic dielectric medium con methed to calculate reflection con wave propagates through an inhomogeneous dielectic layers. Use matrix consisting of Coefficient.
