Methods

ConfigureEMLookupTable(string)

Configures a lookup table and initialises the model type depending if the lookup table is valid.

public override bool ConfigureEMLookupTable(string filename)

Parameters

filename string

The full path name (or local file) of the filename to use as a lookup table.

Returns

bool

A successful lookup table flag

DisableEMLookupTable()

Disables the EM Lookup Table

public override void DisableEMLookupTable()

GetLoadedRFPattern(double, double, double, bool)

Gets the currently loaded RF pattern and returns the data in degrees as an array from 0 to 360.

public double[] GetLoadedRFPattern(double from, double to, double increment, bool useFloor = true)

Parameters

from double

[deg] The starting angle to search (inclusive)

to double

[deg] The final angle to search (inclusive)

increment double

[deg] The increment between angles

useFloor bool

A flag whether to add the floor of the value

Returns

double[]

The RF pattern array from 0 to 360

OnBegin(double)

Called when the 'Component' is beginning

protected override void OnBegin(double time)

Parameters

time double

current time (seconds)

OnFinish(double)

Called when the 'Component' is finishing

protected override void OnFinish(double time)

Parameters

time double

current time (seconds)

UpdatePointingloss(double)

Updates the pointing loss of the antenna based on the angle of the component.

public void UpdatePointingloss(double angle)

Parameters

angle double

[deg] The angle to calculate the pointing loss to
