### Error from integration using mpmath quad

Hello all,

I am trying to solve an integral with one variable kx and then I need the result from that integral to be evaluated in a point defined by x,y coordinates.

The code I am using is the following:

import numpy as np
from numpy.lib.scimath import sqrt
from mpmath import *
import matplotlib.pyplot as plt
mp.dps = 15

f = 8500
rho = 1.225
c0 = 343
Omega = 2*np.pi*f
k = Omega/c0
Z = -426

integrandReal = lambda kx, x, y: np.real(((2*sqrt(k**2 - kx**2)*Z)/(sqrt(k**2 - kx**2)*Z + Omega*rho))*((np.exp(1j*(kx*x + sqrt(k**2 - kx**2)*y)))/(sqrt(k**2 - kx**2))))
integrandImag = lambda kx, x, y: np.imag(((2*sqrt(k**2 - kx**2)*Z)/(sqrt(k**2 - kx**2)*Z + Omega*rho))*((np.exp(1j*(kx*x + sqrt(k**2 - kx**2)*y)))/(sqrt(k**2 - kx**2))))

integral = lambda x, y: quad(integrandReal, [-100*k, 100*k], [x], [y])  + 1j*quad(integrandImag, [-100*k, 100*k], [x], [y])
G = integral(0,0)

My problem is that for any value of x and ythat I use I get:

mpc(real='0.0', imag='0.0')

I appreciate any help to solve this!
