High frequency meta-ferroelectrics by inverse design

Composites with subwavelength features exhibit effective properties that depend on microstructure morphology and materials, which can be adjusted to obtain enhanced characteristics. We detail the systematic design of electromagnetic metamaterials composed dielectric inclusions in a ferroelectric matrix that, under an applied voltage, present optimized tunability higher than bulk due nonlinear local electric field enhancement. The effect volume fraction, losses, biasing homogenized is investigated analysis photonic band diagram carried out, providing frequency dependence anisotropic index tunability. Such metaceramics used microwave antennas components reconfigurability reduced power consumption.
