Abstract
We have fabricated a three-dimensional (3D) microlattice, composed of orthogonal polymer rods along three dimensions and featured with a sub-millimeter scale size, with a photopolymerizing 3D printer. The reflection and transmission spectra of the microlattice have been measured in terahertz time-domain spectroscopy and compared with numerical simulations. Due to Debye relaxation loss of the constituent photopolymer, the microlattice gives rise to absorption in the measured frequencies. In particular, the absorption modulation is observed across the bandgap, corresponding to the lower/upper band edges, and is a straightforward manifestation of the Borrmann effect.
