Resonant properties of dielectric metamaterials

We report the results of a study of dielectric structures consisting of higher-permittivity posts embedded periodically in a lower-permittivity host matrix. Such structures can be fabricated by using low temperature co-fired ceramic (LTCC) technology, which allows us to co-process different dielectrics in a single module. We simulate the transmission and reflection characteristics, as well as the field distribution in these structures, and show that they exhibit unusual electromagnetic properties because of interaction between the neighboring dielectric resonators at their respective resonant frequencies.
