Freespace.characteristic_impedance

Characterisitc impedance

The characteristic_impedance can be either a number, array-like, or a function. If it is a function is must take no arguments. The reason to make it a function is if you want the characterisitc impedance to be dynamic, meaning changing with some attribute of the media. See __init__() for more explanation.

Returns :characteristic_impedance : numpy.ndarray
