SOLVED: Consider TE modes in a planar dielectric slab waveguide of thickness 𑑠= 1 μm, for which the numerical aperture is NA = 0.171.(a) Determine the single-mode cutoff wavelength, i.e., the wavelength above which the waveguide is only supporting a single TE mode.(b) How many TE modes would be supported at this wavelength if the thickness were 10 μm instead of 1 μm?

SOLVED:The longitudinal phase velocity in the dielectric slab waveguide of the preceding problem is vp=ω/ kt=c /(n1 cosθp) . Intermodal dispersion occurs because the dielectric media have dispersion and also because the group velocity differs intrinsically for different modes. (a) Making the approximation that the dielectrics' dispersion can be neglected, show that the group velocity vs=d ω/ d kz for the TEp mode is vk=(c cosθρ)/(n1)[(1 βp a)/(cos^2 θp βp a)] where θρ, is the eigenangle of the p

A parallel plate capacitor is charged by a battery. After sometime the battery is disconnected and a dielectric slab with its thickness equal to the plate separation is inserted between the plates. How will (i) the capacitance of the capacitor, (ii) potential difference between the plates and (iii) the energy stored in the capacitor be affected?Justify your answer in each case. - 8z6rmhqgg
