| Outline of Final Research Achievements |
We have investigated a method to achieve band-selective electromagnetic shield in view of keeping required wireless communications and intercepting undesired electromagnetic waves in medical institutions. We have noticed the band-gap (band-stopping) characteristic of photonic crystal, which is a kind of periodic structures, and have performed computer simulations concerned with the reflection and transmission of electromagnetic waves by adapting two-dimensional and three-dimensional non-metal photonic crystals to microwave band. We have analyzed the frequency and spatial characteristics for some kinds of periodic structures, and have obtained fundamental data for making band-selective shielding materials. The trial production of the materials and the experiment for evaluating the characteristic of them are future subjects.
