Two types of one-dimensional photonic crystals composed magnetic and dielectric materials (magnetophotonic crystals) driven, respectively, by Kerr (reflection) Faraday (transmission) modes were constructed. Their optical magneto-optical (MO) properties studied in detail to confirm our theoretical results showing the large effects media originating localization light. For Kerr-mode operation, films with (SiO2/SiN)×k/Co/(SiN/SiO2)×k (k: number layers) structures fabricated, while for...

The magneto-optical (MO) Faraday effect of one-dimensional photonic crystals (1D-PCs) composed Bi-substituted yttrium–iron–garnet films and dielectric such as SiO2 TiO2 were studied theoretically. Because considerable localization light, these media exhibit a very large MO effect. For instance, when the film structure is chosen to be appropriate for supporting 1D-PC can possess huge rotation angle reaching −28 deg/μm at λ=1.15 μm. analysis reveals that characteristics are almost governed by...

Biallelic frameshift mutations produced sinistrally coiled offspring generation after generation, in otherwise totally dextral genetic background. This sought for over century. We also...

We have formulated the conditions in which dipolar surface plasma resonance is excited by light waves composites containing nanometer-sized, $n$-fold multicore-shell structured particles (referred henceforth as ``nano-onions'') dispersed matrices. The nano-onions ellipsoidal shape and an arbitrary layer number $n$, contain shell(s) (or core) of a metal having Drude type free electrons responsible for oscillation. By solving quasistatic potential boundary problem nano-onion that exposed to...

We synthesized four kinds of magnetite particles having average sizes 7, 18, 40, and 80nm investigated their heating ability when they were dispersed in an agar gel exposed to ac magnetic field at 120kHz, a noninvasive frequency for anticancer hyperthermia. The 18nm diameter gave the highest ability, though exhibited narrow hysteresis loops as compared diameters 40 80nm. This indicates that loss does not contribute much heat rise by 120kHz field, Néel relaxation is dominantly contributing...
