Detailed Description

struct holding the azimuth and inclination angles of spherical coordinates.

The notation is the one used in "Antenna Theory - Analysis and Design", C.A. Balanis, Wiley, 2nd Ed., section 2.2 "Radiation pattern". This notation corresponds to the standard spherical coordinates, with phi measured counterclockwise in the x-y plane off the x-axis, and theta measured off the z-axis.

Constructor & Destructor Documentation

ns3::Angles::Angles

(

)

default constructor, will initialize phi and theta to zero

Definition at line 60 of file angles.cc.

ns3::Angles::Angles	(	double	phi,
		double	theta
	)

this constructor allows to specify phi and theta

Parameters

phi	the azimuth angle in radians
theta	the inclination angle in radians

Definition at line 67 of file angles.cc.

ns3::Angles::Angles

(

Vector

v

)

this constructor will initialize phi and theta by converting the given 3D vector from cartesian coordinates to spherical coordinates

Parameters

v	the 3D vector in cartesian coordinates

Definition at line 74 of file angles.cc.

ns3::Angles::Angles	(	Vector	v,
		Vector	o
	)

this constructor initializes an Angles instance with the angles of the spherical coordinates of point v respect to point o

Parameters

v	the point (in cartesian coordinates) for which the angles are determined
o	the origin (in cartesian coordinates) of the spherical coordinate system
