Magnetism of Cu_6 Ge_6 O_{18}-x H_2 O (x = 0 ~ 6), a compound of the one-dimensional Heisenberg model with competing antiferromagnetic interactions
Masashi Hase, Kiyoshi Ozawa, Norio Shinya
We measured the magnetic susceptibilities of CuGeO-xHO (). Susceptibility above the antiferromagnetic (AF) transition temperature () agr…

A Novel Photonic Material for Designing Arbitrarily Shaped Waveguides in Two Dimensions
Hiroshi Miyazaki, Masashi Hase, Hideki T. Miyazaki +2
We investigate numerically optical properties of novel two-dimensional photonic materials where parallel dielectric rods are randomly placed with the restriction that the distance…

Isotropic photonic band gap and anisotropic structures in transmission spectra of two-dimensional 5-fold and 8-fold symmetric quasiperiodic photonic crystals
Masashi Hase, Hiroshi Miyazaki, Mitsuru Egashira +3
We measured and calculated transmission spectra of two-dimensional quasiperiodic photonic crystals (PCs) based on a 5-fold (Penrose) or 8-fold (octagonal) symmetric quasiperiodic p…
