Coaxial Cable, Three Layers

Coaxial Cable, Three Layers

Coaxial Cable Netlist Format

The netlist syntax for a coaxial cable, three layers is:

Axxxx n1 n2 COMPONENT=coax_cable_threelayer
+ DI=val DO=val D1=val D2=val P=val RB=val
+ ER1=val ER2=val ER3=val TAND1=val TAND2=val TAND3=val

n1 and n2 are the nodes attached to the cable. The entry COMPONENT=coax_cable_threelayer is required.

**Coaxial Cable, Three Layer Parameters**
Parameter	Description	Unit	Default
DI	Diameter of inner conductor	Meter	0.25e-3
DO	Inner diameter of outer conductor	Meter	1e-3
D1	Diameter to edge of layer 1	Meter	0.5e-3
D2	Diameter to edge of layer 2	Meter	0.75e-3
P	Physical length of cable	Meter	0.0127
ER1	Dielectric constant of medium 1	None	2.0
ER2	Dielectric constant of medium 2	None	5.0
ER3	Dielectric constant of medium 3	None	8.0
TAND1	Dielectric loss tangent for medium 1	None	0.0
TAND2	Dielectric loss tangent for medium 2	None	0.0
TAND3	Dielectric loss tangent for medium 3	None	0.0
RB	Conductor resistivity	mOhm-cm	0.0

Coaxial Cable, Three Layer Netlist Example

Acable1 net_34 net_27 DI=0.00 1 DO=0.003 D1=-.5e-7 D2=0.75e-3
+ P=.10 RB=1.64 ER1=2.1 ER2=5.2
+ component=coax_cable_threelayer
