(a) 1D conceptual scheme of arraying in which each lattice point is defined arraying. Overlapping of locally melting particles enables accurate positioning of each particle. (b) Schematic of the 3D particle assembly method.
Terahertz wave properties of /PE composites at 1 THz. Filled and open circles represent dielectric constants and transmittances, respectively.
Scanning-electron microscopy images of the monosized spherical particles of /PE. Inset shows the histogram of particle sizes.
Micrographs of the fabricated diamond structure that has 16 ML. The structures were arrayed from right to left and from front to back in the image. (b) and (c) show the details of the welded contact points, which are indicated by arrows in (a). The scale bars in (a), (b), and (c) represent 1 mm and , respectively.
Transmission spectra of the fabricated diamond structure in the direction. Light-gray and dark-gray bands represent the theoretical frequency ranges of the stop gap and full bandgap calculated by using the plane-wave expansion method. The spectrum obtained experimentally (solid line) is compared with that obtained from the finite-difference time-domain simulation (dashed line).
