Hi Use These Commands As a Sample
clear all
kr=1*1;
ki=1*1;
phi=1*pi/4;
xmax=15;
xmin=-4;
delx= 0.1;
x=[0:delx:xmax];
x2=[xmin:delx:xmax];
framemax=248;
M=moviein(framemax);
set(gcf,'Position',[100 100 640 480]);
for n=1:framemax
E=exp(-0.3.*x.*ki).*cos(kr.*x-2*pi*n/framemax);
H=exp(-0.3.*x.*ki).*cos(kr.*x-2*pi*n/framemax+phi);
S=E.*H;
figure(1)
whitebg([1 1 1]);
plot(x,E,'r','LineWidth',5);
hold on
plot(x-round(100*H)/30,-H,'b','LineWidth',5);
plot(x,S,'g','LineWidth',3);
legend('E-field','H-field','Power Density')
plot(x2,0.3*x2,'k','LineWidth',3);
plot(0*x2,x2,'k','LineWidth',3);
hold off
axis([-4 10 -1.1 1.5])
title('Wave Propogation In Very Lossy Media','fontsize',18)
M(:,n)=getframe(gcf);
end
clf reset
set(gcf,'Position',[100 100 800 600])
axis off
movie(M,3,1)
close all
Hope It helped...
