Abstract
A vehicle assembly including a radar sensor configured to emit radar waves over a range of wavelengths with an arrangement of layers placed opposite the radar sensor, including a first subset of layers configured to perform an optical function, each layer having a refractive index and a thickness, and a second subset of layers configured to provide protection for the first set of layers, each layer having a refractive index and a thickness. The total thickness of the second subset of layers is dimensioned so that the total thickness of the arrangement of layers is equal to m times a wavelength of the range divided by twice the equivalent refractive index of the first subset of layers and of the second subset of layers, times the cosine of a refracted angle corresponding to the angle of incidence of the radar waves, where m is an integer.
