microstrip synthesis with refinement (calculates w/h from Z)
[u,N] = mstripr(er,Z0,per)
[u,N] = mstripr(er,Z0) (equivalent to per=0.2)
relative permittivity of substrate
desired characteristic impedance
percent accuracy for Z0 and u, typically per is in range (0.1,0.2)
width-to-height ratio = w/h
number of refinement iterations
mstripr(er,Z0) performs microstrip synthesis with refinement (calculates w/h from Z)
