We investigate optical properties of the interface between the anisotropic metamaterial with hyperbolic dispersion and the isotropic dielectric. With material dispersion, a comprehensive theory is constructed, and the hyper-lens effect that the evanescent wave can be converted into the radiative wave is confirmed. At the inverse process of hyper-lens, we find a mechanism to compress and stop (slow) light at wide frequency range, which can be used as a removable memory or a light trap. All theoretical results are demonstrated by finite-difference time-domain simulation.

    In this work, we use thin dielectrics to reduce the Al/n-GaAs effective barrier height ([uppercase_phi_synonym]B,eff) of metal-insulator-semiconductor (MIS) contacts. We investigate the use of atomic layer deposition of HfO2, Al2O3, TiO2, ZrO2, and bilayer high-κ dielectrics and confirm there...

    Far-field directional radiation of a single dipole in a cuboid slot is investigated in the presence of a dielectric substrate. Due to strong near field coupling between the dipole source and the surfaces of the slot and the dielectric, the far-field radiation shows strongly anisotropic pattern...

    Ab initio calculations reveal that ultrashort-period epitaxial KNbO3/(KTaO3)m superlattice exhibits typical ferroelectricity when m=1 or 2; while it becomes paraelectric when m>=3. We observe considerable and tantamount dipole moment in each cell, which can be attributed to the continuity of...

    Recent experiments revealed unusual dielectric behaviors of Pb(Mg1/3Nb2/3)O3 originated from polar nanoregions (PNRs). Thus, Pauli's master equation is adopted to investigate the distinct dielectric responses, correlation strength, and volume evolutions of static and dynamic PNRs. Our findings...
