Modeling E field from gaussian beam at a given z value

I am trying to make a 2D model of the electric field of a Gaussian beam at a given z value, such that the Gaussian beam's electric field appears to be a circular distribution on the x-y plane, and observe the electric field interaction between a gold nanoparticle with this electric field.
I am using the Gaussian beam equation, with a fixed z arbitrary value of z:
E(x,y)= (w0/w)*exp(-((x^2)+(y^2))/(w^2))*exp(-j*k*((x^2)+(y^2))/(2*R_curvature))*exp(j*(atan(z/z0)))
under the Electromagnetic waves, frequency domain.
I have simulated the Gaussian beam E field (at a single z value) on the x-y plane by placing the Gaussian beam equation under the Background electric field at the x direction. Is it correct to say that since the Gaussian E field is dependent on both x and y values, placing the equation in either the x or y field of the background electric field generates the same result?
Sorry if this question sounds elementary, I am new to this software and this is my very first project! Much thanks!
