Abstract	:	Significant interest in automotive radar sensors for adaptive cruise control (ACC) has been shown in recent years. These sensors use a millimeter-wave band from 76 to 78 GHz. In this thesis, a metamaterial that acts as a strongly resonant absorber at millimeter-wave is presented. The design consists of a bilayer unit cell which allows for the maximization of absorption through independent tuning of the electrical permittivity and magnetic permeability. A simulated absorptivity of 99.95% at 76.4 GHz is demonstrated. These metamaterials are promising candidates as absorbing elements for use in radar ACC sensors, due to their relatively high absorption coefficient, compact design, and narrow band response.
