Code 2.4: Reflection by Two-Layer Composite

Code Name: Refl_TwoLayerComposite.m

Description: Code computes reflection by a two-layer composite with planar boundaries. Medium 1 is air with ε₁ = 1.

Input Variables:

ε₂ = ε₂ ^' - jε₂ ^'':	Dielectric constant of middle layer (unitless)
ε₃ = ε₃ ^' - jε₃ ^'':	Dielectric constant of bottom layer (unitless)
Θ₁:	Incidence angle in medium 1 (degrees)
d:	Thickness of middle layer (m)
f:	Frequency (GHz)

Output Products:

ρ:	Reflection coefficient (unitless)
Γ:	Reflectivity (unitless)
Plot:	\|ρ\| or Γ as a function of d
