I have an equation for an electric and magentic wave. Very simply they look like

and

. where A, ω, k are just constants. I want to plot these in a 3-dimensional space. I'm not sure if I even need to include the time t since I only need a snap shot at one instance in time. I have tried surface plot and fplot3 to no success. I want something that looks like:

I’m not certain what you want.

Try this:

E = 2;
H = 3;
t = linspace(0, 2*pi);
omega = 2;
k = pi/2;
x = ones(size(t));
c = cos(omega*t - k*x);
figure
patch([t fliplr(t)], [c zeros(size(c))], [zeros(size(t)) zeros(size(t))], 'b')
hold on
patch([t fliplr(t)], [zeros(size(t)) zeros(size(t))], [c zeros(size(c))], 'r')
hold off
grid on
view(40, 40)
