Investigation of Microstrip Lines Dispersion by the FDTD Method

Elektronika ir Elektrotechnika, 2011
The technique based on the FDTD method for calculation of the dispersion characteristic of the microstrip transmission line (MSTL) is proposed. Accuracy of the suggested technique is checked up by comparison of results of calculation of the dispersion characteristics with results of measurements executed by other researchers.

Metalens‐Enabled Double‐Helix Point Spread Function for Multifunctional Imaging

Advanced Physics Research, EarlyView.
A single metalens is employed to generate a double‐helix point spread function (DH‐PSF). At the design wavelength, the PSF rotation angle varies linearly with depth, while the lobe spacing follows an inverse dependence on axial position. At a fixed depth, the lobe spacing further exhibits a linear dependence on wavelength due to dispersion.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

Laser &Photonics Reviews, EarlyView.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...
