10.4 Metal and Glass Components
Metallodielectric photonic crystals are composed of periodically arranged magnetic
materials. These crystals form forbidden bands to reflect electromagnetic waves of
wavelengths comparable to the lattice constant through Bragg diffraction [7, 8].
The electromagnetic waves in terahertz frequency ranges were verified to synchronize with the collective vibration modes of various harmful substances; therefore,
spectroscopic technologies are expected to be applied to sensors for real-time detection of toxic materials [9]. Diamond photonic crystals with coordination number
4 composed of the metallic glass dispersed oxide glass were fabricated by laser
scanning stereolithography and applied to the terahertz wave sensor devices.
The diamond lattice structures composed of magnetic rods with an aspect ratio
of 1.5 were designed using the computer graphic software, as shown in Fig. 10.5.
The lattice constant was 500 µm in length. The whole structure was 5 × 5 × 5 mm
consisting of 10 × 10 × 10 unit cells. The electromagnetic wave propagation and
spatial wave diffractions were simulated along Maxwell’s equations using the plane
