| Stdio-Wcalc: coax_calc coax_calc - Coaxial transmission line analysis ## SYNOPSIS coax_calc a b c t rho_a rho_b er tand len f ## PARAMETERS ### INPUT PARAMETERS a : radius of inner conductor (meters) b : inner radius of outer conductor (meters) c : offset of the inner conductor from the center (meters) t : thickness of shield (meters) rho_a : resistivity of inner conductor (ohms/meter) rho_b : resistivity of outer conductor (ohms/meter) er : relative permitivitty of dielectric tand : loss tangent of dielectric len : physical length of line (meters) f : analysis frequency (Hertz) ### OUTPUT VALUES L : calculated inductance per length (Henries/meter) R : calculated resistance per length (Ohms/meter) C : calculated capacitance per length (Farads/meter) G : calculated conductance per length (Siemens/meter) lc : conductor loss (dB/meter) ld : dielectric loss (dB/meter) fc : TE10 cutoff frequency (Hz) em : Max Electric Field (Volts/meter) ## DESCRIPTION Function to analyze the electrical characteristics of a coaxial transmission line. The physical dimensions of the line are given as inputs and the characteristic impedance and incremental circuit model elements are calculated. ## EXAMPLE
    * 50.000 ohms
