Noble metal nanoparticles like Au have long been admired for their brilliant colour,
significantly influenced by plasmon resonance. When embedded in metal oxides, they …

Extensions of finite-difference time-domain (FDTD) and finite-element time-domain (FETD)
algorithms are reviewed for solving transient Maxwell equations in complex media. Also …

Using a semianalytic guided-mode expansion technique, we present theory and analysis of
intrinsic propagation losses for topological photonic crystal slab waveguide structures with …

A concise formulation of the frequency-dependent finite-difference time-domain (FDTD)
method is presented using the trapezoidal recursive convolution (TRC) technique for the …

A surface plasmon resonance (SPR) waveguide sensor with a thin InSb layer adopted for
the sensing section is proposed in the terahertz region. First, the eigenmode analysis is …

Flat left-handed metamaterial (LHM) lens can generate appropriate focusing spot in
biological tissue as required in microwave tumor hyperthermia treatment. By using single flat …

Detailed frequency-dependent formulations are presented for several efficient locally one-
dimensional finite-difference time-domain methods (LOD-FDTDs) based on the recursive …

The accuracy of finite-difference time-domain (FDTD) modelling of left-handed
metamaterials (LHMs) is dramatically improved by using an averaging technique along the …

Using finite-difference time-domain (FDTD) simulations we investigate the propagation of
light pulses in waveguides having a core made of a negative-refractive-index metamaterial …

We compare the properties of sub-wavelength imaging in the visible wavelength range for
metal–dielectric multilayers operating in the canalization and the resonant tunnelling …
