Metamaterial Embedded Optical Devices for Millimeter Wave and Terahertz Applications

We propose a unique metamaterial embedded geometrical optics device formed through the fusion of a frequency selective metamaterial with an optical parabolic reflector for frequency selective focusing function. This device combines individual properties of an optical device (parabolic mirror) and photonic device (metamaterial) in a single device. The fabricated device operates in the millimeter wave frequency range. Simulation and measurement results using terahertz continuous-wave spectrometer validate its functionality and performance. The device is fabricated using a combination of 3D printing and metal deposition. This approach will open the door to a new generation of metamaterial embedded geometrical optics (MEGO) devices. It will also enables us to have more compact Terahertz spectroscopy setup.
