AddLumpedElement

AddLumpedElement(CSX, name, direction, varargin)

Full definition:

function CSX = AddLumpedElement(CSX, name, direction, varargin)

Add a lumped element property to CSX with the given name. Remember to add at least one or more box primitive to any property.

arguments:

  • direction: 0,1,2 or ‘x’,’y’,’z’ for the orientation of the lumped element

optional arguments:

  • ‘R’, ‘C’, ‘L’: definition of the lumped element properties

  • ‘Caps’: 0 or 1 to (de)activate lumped element caps (1=default) If Caps are enable, a small PEC plate is added to each end of the lumped element to ensure contact to e.g a microstrip line

  • ‘LEtype’: 0 = parallel (default), 1 = series Parallel: R, C and L are all in parallel (standard lumped capacitor/resistor/LC tank). Series: R, L and C are in series (use this for a series inductor, e.g. to tune antenna length).

examples:

%lumped element capacitor in y-direction with 1pF
CSX = AddLumpedElement( CSX, 'Capacitor', 1, 'Caps', 1, 'C', 1e-12 );
CSX = AddBox( CSX, 'Capacitor', 0, [0 0 0], [10 10 10] );

%series inductor in x-direction with 10nH (e.g. to tune antenna length)
CSX = AddLumpedElement( CSX, 'Inductor', 0, 'Caps', 1, 'L', 10e-9, 'LEtype', 1 );
CSX = AddBox( CSX, 'Inductor', 0, [0 0 0], [10 10 10] );
