function	surface_normal_rim (in rho, in phi, in z, in f, in d, in R)

Detailed Description

Computes the unit normal vectors on the circular rim of a parabolic dish.

This function calculates the normal vectors in Cartesian coordinates for points located on the rim extension of a parabolic reflector, based on geometry derived from the main paraboloid and the added rim.

Parameters

rho	Radial coordinate [m]
phi	Azimuthal angle [rad]
z	Z-coordinate [m]
f	Focal length of the dish [m]
d	Diameter of the dish [m]
R	Radius of the circular rim [m]

Return values

x	X component of the unit normal vector
y	Y component of the unit normal vector
z	Z component of the unit normal vector
