v=343; % m/s
f=1000; % Hz
w=2*pi*f; % angular frequency
lambda=v/f; % wavelength
k=2*pi/lambda; % k-vector
x=-2:0.01:2;
y=x;
[X,Y]=meshgrid(x,y);
A=1; % amplitude
t=linspace(0,pi,50);
for a=1:length(t)
r=sqrt(X.^2+Y.^2);
E=(A./r).*exp(1i.*(k.*r-w.*t(a))); % wave equation
pcolor(X,Y,real(E)); shading flat; axis equal;
caxis([-5 5]);
drawnow;
end
Is this what you are looking for ?
