Hi.
please i need to plot the normalized phase velocity Vp/c with wave propagation angle alpha by newton method in matlab (numerical dispersion allen taflove susan).
where is the probleme in my programme matlab???
please i need to plot the normalized phase velocity Vp/c with wave propagation angle alpha by newton method in matlab (numerical dispersion allen taflove susan).
Code:
lunda0=1;
Dx=lunda0/5;
c=3e8;
omiga=(2*pi*c)/lunda0;
Dt=Dx/(2*c);
alpha=1:1:90;
k=2*pi;
A=Dx*cos(1:1:90)/2;
B=Dx*sin(1:1:90)/2;
C=((Dx/(c*Dt))^2)*(sin(omiga*Dt/2))^2;
for i=1:3
k=k-((sin(A.*k)).^2+(sin(B.*k)).^2-C)./(A.*sin(2.*A.*k)+B.*sin(2.*B.*k))
end
kfinal(alpha)=k;
Vp=2*pi*c./kfinal(alpha);
x=Vp./c;
plot(alpha,x)where is the probleme in my programme matlab???
