Description :-

Objective of the program is to solve for the steady state voltage distribution of the inside region of a microstrip and then using that obtain the electric field distribution in the region using quiver plot. The
microstrip comprises of a region given by x from 0 to 7 units and y from 0 to 2 units in the coordinate system bounded by four capacitor plates on all the sides of the region. The region comprises of a material with relative permittivity 1 at y from 0 to 1 units and a material of relative permittivity 9.6 at y from 1 to 2 units. The microstrip extends indefinitely in the z-direction. The sides of the region are given Dirichlet boundary condition. A horizontal microstrip line is placed at the center of the region. The microstrip is excited with a voltage of 1 Volt and all surrounding plates are maintained at 0 Volts.
