dguide

TE modes in dielectric slab waveguide

Calling Sequence

[be,kc,ac,fc,err] = dguide(f,a,n1,n2,Nit)
[be,kc,ac,fc,err] = dguide(f,a,n1,n2)     (equivalent to Nit=3)

Parameters

f

frequency in GHz

a

half-width of slab in cm

n1,n2

refractive indices of slab and cladding (n1>n2)

Nit

number of Newton iterations (default Nit=3)

be

propagation wavenumbers of the supported TE modes in rads/cm

kc

cutoff wavenumbers inside slab in rad/cm

ac

cutoff wavenumbers outside slab in nepers/cm

fc

cutoff frequencies below f in GHz

err

approximation error in determining kc,ac

Description

dguide(f,a,n1,n2,Nit) determines TE modes in dielectric slab waveguide.

Examples

f = 30; a = 0.5; n1 = 2; n2 = 1; Nit = 3;
[be,kc,ac,fc,err] = dguide(f,a,n1,n2,Nit)
