PROJECT TITLE :
We tend to present a terahertz transmission blaze-grating, that can be fabricated, simply, cost efficiently and in large numbers using compression molding of micro-powder. The diffraction properties of the grating are derived by simulation of electro-magnetic field scattering and are compared with angle-dependent measurements obtained in an exceedingly terahertz time-domain setup. An excellent match between simulation and measurement is found, demonstrating the flexibility of the terahertz transmission blaze-grating for spatial dispersion of terahertz waves. Therefore, this and similar terahertz transmission blaze-gratings can be used as dispersive elements for applications like spectrometers or novel THz imaging systems.
