Tricontrollable pixelated metasurface for absorbing terahertz radiation
Pankaj Kumar, Akhlesh Lakhtakia, Pradip Kumar Jain
The incorporation of materials with controllable electromagnetic constitutive parameters allows the conceptualization and realization of controllable metasurfaces. With the aim of…
On Dyakonov-Voigt surface waves guided by the planar interface of dissipative materials
Chenzhang Zhou, Tom G. Mackay, Akhlesh Lakhtakia
Dyakonov-Voigt (DV) surface waves guided by the planar interface of (i) material which is a uniaxial dielectric material specified by a relative permittivity dyadic with eigenv…
Compound Guided Waves That Mix Characteristics of Surface-Plasmon-Polariton, Tamm, Dyakonov-Tamm, and Uller-Zenneck Waves
Francisco Chiadini, Vincenzo Fiumara, Antonio Scaglione +1
Solutions of the boundary-value problem for electromagnetic waves guided by a layer of a homogeneous and isotropic (metal or dielectric) material sandwiched between a structurally…
On Direct and Indirect Scattering Approaches for Homogenization of Particulate Composites
Akhlesh Lakhtakia
Theoretical formalisms for the homogenization of particulate composites are identified as following either the direct scattering approach (DSA) or the indirect scattering approach…
On Percolation and Circular Bragg Phenomenon in Metallic, Helicoidally Periodic, Sculptured Thin Films
Akhlesh Lakhtakia
The concept of local homogenization is invoked in the visible and the sub-visible frequency regimes to estimate the permittivity dyadics of a thin-film helicoidal bianisotropic med…
Electromagnetic modeling of near-field phase-shifting contact lithography with broadband ultraviolet illumination
Fei Wang, Katherine E. Weaver, Akhlesh Lakhtakia +1
Near-field phase-shifting contact lithography is modeled to characterize electromagnetic absorption in a photoresist layer with one face in contact with a quartz binary phase-shift…
