EM wave propagation lossy media 3D matlab code

Please help me to write this code in 3-D

t=0:0.001:10;
z=0:0.0005:5;
eta=377;
theta=pi/2;
E0=50;
a=0;
u=1.256*(10.^-6);
e=8.854*(10.^-12);
f=600000000;
w=2*pi*f;
b=w*((u*e).^0.5);
E=E0/eta;
H=E*exp(-a*z).*cos(w*t-b*z-theta);
Ez=E0*exp(-a*z).*cos(w*t-b*z);
figure(1);
subplot(211),plot(z,H,'r');
xlabel('Dispalcement(metres)');
ylabel('Magnetic Field Intensity(H)');
title('Plane wave propagation in Lossy medium');
subplot(212),plot(z,Ez,'g');
xlabel('Dispalcement(metres)');
ylabel('Electric Field Intensity(H)');
title('Plane wave propagation in Lossy medium');

3d image for this?

try this

plot3(z,H,Ez);

Yeah well [], give the code in 3D []

Instead of spewing profanity you could also have tried running this code, at which point you would have noticed that this code is already for the 3D case.
