Microstrip Wizard
ICON: 
MENU: Tools → Transmission Line Wizards → Microstrip Line
MODULE(S): EM.Tempo, EM.Picasso, EM.Ferma
FUNCTION: Creates the parameterized geometry of a microstrip line segment of a specified characteristic impedance on a conductor-backed single-layer dielectric substrate in the project workspace
SPECIAL CASES OR EXCEPTIONS: In EM.Tempo and EM.Picasso, this wizard creates a one-port open-ended microstrip transmission line segment. In EM.Ferma, it sets up a 2D solution plane for quasi-static analysis of the microstrip transmission line. The width of the microstrip line is determined based on the specified characteristic impedance. It may be replaced by a numeric value instead.
PYTHON COMMAND(S):
emag_microstrip_tempo(h,er,z0,strip_len,feed_len,sub_len,sub_wid,draw_substrate)
emag_microstrip_picasso(h,er,z0,strip_len,feed_len)
emag_microstrip_ferma(h,er,z0,box_multiplier,draw_substrate)

FUNCTION: Creates the parameterized geometry of a coaxial line segment of a specified characteristic impedance with a dielectric core in the project workspace
SPECIAL CASES OR EXCEPTIONS: In EM.Tempo, this wizard creates a one-port open-ended coaxial transmission line segment. In EM.Ferma, it sets up a 2D solution plane for quasi-static analysis of the coaxial transmission line. The radius of the outer conductor is determined based on the specified characteristic impedance. It may be replaced by a numeric value instead.
PYTHON COMMAND(S):
emag_coax_2port_tempo(er,z0,r_inner,len)
emag_coax_ferma(er,z0,r_inner)

MODULE(S): EM.Tempo
FUNCTION: Creates the parameterized geometry of a rectangular waveguide segment slightly above the cutoff at the center frequency of the project
SPECIAL CASES OR EXCEPTIONS: This wizard creates a one-port open-ended rectangular waveguide segment in EM.Tempo. The width of the waveguide is set slightly larger than half its cutoff wavelength for the dominant TE10 mode. The height is set equal to half its width. Both the width and height can be replaced by arbitrary numeric values.

|---|---|---|---|---|
| wg_len | real numeric | meters | - | length of the waveguide segment |
| port_offset | real numeric | meters | - | distance between port plane and the first open end of the waveguide |
