Function Documentation

interpFrame()

np.ndarray PyPO.System.System.interpFrame	(		self,
		str	name_fr_in,
		str	name_field,
		str	name_target,
		str	name_out,
		FieldComponents	comp = FieldComponents.NONE,
		str	method = "nearest"
	)

Interpolate a frame and an associated field on a regular surface.

The surface should be the target on which the input frame is calculated. The "name_field" should be an associated field, calculated in the same hybrid propagation as "name_fr_in".

Parameters

name_fr_in	Name of input frame.
name_field	Name of field object, propagated along with the frame by multiplication.
name_target	Name of surface on which to interpolate the field.
name_out	Name of output field object in target surface.
comp	Component of field to interpolate. Instance of FieldComponents enum object.
method	Method for the interpolation.

Returns

out Complex numpy array containing interpolated field.

runHybridPropagation()

def PyPO.System.System.runHybridPropagation	(		self,
		dict	hybridDict
	)

Perform a hybrid RT/PO propagation, starting from a reflected field and set of Poynting vectors.

The propagation is done by performing a ray trace from the starting frame into the target surface. Then, the starting reflected field is propagated to the target by multiplying each point on the field by the phase factor corresponding to the travel length of the Poynting vector ray associated to the point on the field. Stores name of resultant field and frame in the internal association dictionary as two associated objects. The name of the association is the surface on which both the target frame and field are defined.

Parameters

hybridDict

A hybridDict dictionary.
