One symmetric and two asymmetric chevron thin films of silver were fabricated by bidepositing oppositely tilted nanorods sequentially via oblique angle deposition. The equivalent electromagnetic parameters of the films for s and p polarizations were retrieved at a wavelength of 639 nm for normal incidence using walk-off and polarization interferometers. Experimental results indicate that the symmetric chevron thin film has the strongest magnetic field reversal among the three different shapes. The coupling of the transverse magnetic field between two separate rods makes the equivalent permeability negative real.
