Hello, I am struggling on this equation since some days. because I followed the theoretical equation of plate response but the plot still not correct. Please could you have a look on my script.

J0i = besselj(0,1i*k*rx);

N0i= besseli(0,1i*k*rx);
t1=0;
t2=0.023;
t3=2*t2;
v1t= v0*(J0+1i*N0-1i*J0i-1i*N0i)*exp(-1i*2*pi*f*t1);
v2t= v0*(J0+1i*N0-1i*J0i-1i*N0i)*exp(-1i*2*pi*f*t2);
v3t= v0*(J0+1i*N0-1i*J0i-1i*N0i)*exp(-1i*2*pi*f*t3);
figure(1)
plot(rx,real(v1t),'r',rx,real(v2t),'b',rx,real(v3t),'g',rx,real(v3t)*0,'k');
break;
Thank you in advance.
