MS Tee, Reference Planes at Center (MSTEEC)

Properties	Description	Units	Default	Range
W1	Width of line connected to node n1	m	Required	> 0
W2	Width of line connected to node n2	m	Required	> 0
W3	Width of line connected to node n3	m	Required	> 0
NSUM	Number of modes considered in the field expansion	none	3	[1,9]
sub	Substrate name	none	Required	string

Notes

1. To get accurate results, the following condition should be satisfied: H/l_g<< 1, where l_g is the guide wavelength in the substrate dielectric.

2. The collinear lines are connected to nodes n1 and n2 and have widths W1 and W2; the perpendicular line is connected to node n3 and has width W3.

3. The n1, n2 reference plane is centered on the width of the line connected to node n3 (width W3).

4. Radiation loss is calculated if HU is not specified in the .SUB statement.

5. If W1 > W2: Node n3 is collinear with W1.

6. If W2 > W1: Node n3 is collinear with W2.

MSTEEC:NAME n1 n2 n3 W1=val W2=val W3=val [NSUM=val] SUB=label

MSTEEC:TEEC1 1 2 3 W1=32MIL W2=48MIL W3=54MIL SUB=SUB1

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