e_near

miepython.field.e_near(abcd, lambda0, d_sphere, m_index, r, theta, phi)

Calculate the electric field in and around a sphere.

Parameters:

• abcd (array) – Mie coefficients [a, b, c, d]

• lambda0 (float) – Wavelength of the incident wave in vacuum.

• d_sphere (float) – Diameter of the sphere.

• m_index (complex) – refractive index at r

• r (float) – Radial distance at which the field is evaluated.

• theta (float) – Polar angle in radians.

• phi (float) – Azimuthal angle in radians.

Returns:

tuple – Electric field components (E_r, E_theta, E_phi).
