TEM wave along a Parallel-plate Transmission Lineconducting-plate y d x w z dielectric slabAt microwave frequencies, it can be fabricated inexpensively on a dielectric substrate using printedcircuit technology. Neglect the fringing fields at the edges of the plates. Consider a y-polarized TEM waves: E= yE y = yE o e γz E H= xH x = x o e γz EE3109 η AppliedTransmission Lines 1ElectromagneticsFor loss-less dielectric,γ = jβ = jω ε η= εwhich satisfies the boundary condition At y = 0 and y = d, Et = 0 Hn = 0Ex = 0 Ez = 0 Hy = 0EE3109 Applied ElectromagneticsTransmission Lines2To calculate the surface charges and surface currents, At y=0,=y n(lower plate) = y At y=d, n(upper plate)y d- + D = y D = εE y = εEo e jβz ρ sl = n E ×H = y × H = ……
