Two series of CIGS thin films were deposited on Molybdenum coated soda lime glass (SLG/Mo) substrates, using physical vapor deposition (PVD) 3-stage process. The 3-stage deposition process was carried out as such during the deposition of the first series of CIGS films the substrate was in linear motion; whereas for th…
The use of hybrid transparent conductive (TC) layer has drawn much attention as a replacement for Indium Tin Oxide (ITO). In this work, Graphene and random Silver NWs have been selected as a hybrid TC to achieve a potential replacement. A simple solution-based process was applied for stacking NWs to Graphene. Understa…
We report the properties of sputtered/co-evaporated thin film iron pyrite as the back contact interface layer of CdS/CdTe solar cells. In our study we have compared the performance of sputter-deposited CdTe devices which utilized either a Cu/Au contact, or an FeS2/Cu/Au contact. Comparing our best devices of each type…
On page 3005, R. Vecchione and co-workers use ultrastable oil/water nano-emulsions as optimal templates for multilayer deposition of several biodegradable polymers at the interface even after 1 year. Small size (down to 100 nm), monodispersion, biosafety and bi-compartmental structure based on a lipophilic core and a…

Highly conductive nominally undoped ZnO (b-ZnO) films represent an attractive alternative for ZnO:Al windows employed in thin film solar cells. In order to assess their suitability for the PV industry, we examine here their stability in various environments. We show that the b-ZnO films can exhibit comparable stabilit…
GRadient INdex (GRIN) optics has revolutionized the field of lens design by providing an unparalleled amount of design freedom, resulting in high-performance optical systems. Unfortunately, this design freedom leads to a large number of parameters in multi-element systems, since the GRIN distributions need to be descr…
In this paper, we propose a method using delay in space to generate orbital angular momentum (OAM) carrying beams. First, l = 1 and l = 2 helicoidal arrays are designed to generate OAM beams by using delay in space. Moreover, utilizing both delays in space and in phase, a crossed array which can generate first-order O…
Chiral structures are composed of periodically arranged asymmetric particles. The asymmetry of chiral particles results in extraordinary properties like negative refraction index, giant optical activity and circular dichroism. Consequently, they have applications in super lens and various polarization controllers. The…
Feynman-Kac stochastic representation for elliptic equations is used to construct the solution of Helmholtz equation within a plasmonic structure. Comparison is shown with the exact solution for the field inside a plasmonic nanosphere driven externally by a vertical electric dipole at optical frequencies where the per…
This paper presents a new type of 3-DOF type combined drive motor, which can realize the rotation and deflection movement. The original type of 3-DOF type combined drive motor in the comparison between the basic structures is given with the working principle, etc. The air-gap magnetic field of the motor is calculated…
This paper presents an effective and accurate approach for the derivation of the dispersion characteristics of impenetrable Metasurfaces (MTSs). This approach is based on a simple representation of the MTS impedance, depending on one parameter only, which is an equivalent quasi-static capacitance. This procedure can b…
In this paper, the wave propagation of a graphene based conductor (GBC) transmission line (TL) and its comparison with a copper TL on a conformal surface is presented. An investigation of the coupling between parallel GBC TLs and copper TLs is also summarized in this work. A 150 mm long TL was initially manufactured o…
In this work, a Luneburg lens operating at 15 GHz is created from water cylinders. The approach uses effective media of water and an iterative dielectric distribution method to achieve the Luneburg lens electromagnetic profile. From the approach, the focusing of energy using the proposed Luneburg lens is shown numeric…
The RIT research group has developed, designed, constructed and tested a diffractive optical element (DOE) lens for gain enhancement and beam shaping. Although the lens is unique in that it is much thinner and lighter, the size proved to be much larger than the antenna dimensions. This paper presents a methodology for…
Ultracapacitor is widely used in EVs for its high performance such as high power density, long cycle life and wide working temperature. However, the frequent use and variation of the operating temperature will affect the performance parameters of ultracapacitor and the variation trend of the ultracapacitor's performan…
We present a new technique for designing low-profile circularly-polarized reflectarrays with broadband true-time-delay (TTD) responses and linearly-polarized feeds. The proposed reflectarray exploits the unit cells of ground-plane-backed, anisotropic miniaturized-element frequency selective surfaces as its spatial tim…
This paper describes a nonlinear Fresnel zone plate reflector designed to operate at 2.8GHz. The alternating Fresnel zones of the reflector are made from two different nonlinear metamaterials: one that reflects like a short circuit at low incident power levels and another that reflects like an open circuit. Both metam…
Conducting loops have been rigorously analyzed in the microwave/RF regime due to their simplicity and versatility. In the terahertz, infrared and optical regimes nanoloops are extremely promising for a variety of applications, including as solar cells or optical sensors. However, due to the complex behavior of metals,…
Magnetoelectric materials exhibit altered permeability with the application of a static electric field. As such magnetoelectric materials have the potential to affect the radiation properties of antennas loaded with such a material. In this paper, we explore the radiation properties of patch antennas loaded with slabs…
