NSUM	Number of modes considered in the field expansion	none	3	[1,9]
sub	Substrate name	none	Required	string

Notes

1. This element corresponds to the case where the outer corner of the right-angle bend is mitered at an angle, such that the edges of the cut are on the intersection of the reference planes and the outer edges of the bend. In the case W1=W2, the angle of the cut is 45° and the miter ratio is 0.5.

2. Reference planes coincide with the inside vertex of the corner.

3. Radiation loss is included if cover is not specified.

Netlist Form

MSBENDC:NAME n1 n2 W1=val W2=val [NSUM=val] SUB=label

Netlist Example

MSBENDC:1 1 2 W1=0.025IN W2=0.005IN SUB=SUB1

where sub1 needs to be defined in the corresponding .sub statement.
