RISInvestigation of a metamaterial slab lens and an imaging system based on an ellipsoidal cavity
A slab metamaterial lens with a refractive index of −1 is capable of producing a perfect image, since it transfers all the plane waves from the object plane to the image plane without creating any distortion in their ...
Vectorial analysis of a surface plasmon mode diffracted by a thick dielectric lens
Using the vectorial form of the Huygen-Fresnel principle, we have studied the diffraction of a surface plasmon mode propagating on a metal-dielectric interface as it passes through a dielectric thick lens. This method, ...
ارتقا جذب سلول های خورشیدی لایه نازک با استفاده از ساختارهای پلاسمونیکی
در این مقاله از پلاسمون های سطحی محلی در نانو ذرات برای جفت شدگی نور به پلاسمون های سطحی در یک لایه نازک فلزی که درون سلول خورشیدی قرار گرفته است استفاده شده است. نتایج شبیه سازی نشان می دهد که با این روش می توان میزان ...
Design of a Microwave Dual-band Filter Using Frequency Selective Surfaces
A dual-band frequency selective surface (FSS) made of double ring is presented. The design has been carried out with one layer of FSS. In the first step, two single band FSSs with different radii rings were designed for ...
Excitation of Surface Plasmons in Metallic Thin Films Using Nanoparticle Arrays
In this paper, a device for coupling light into symmetric and asymmetric surface plasmon modes in a metallic thin film is presented. This device consists of a two-dimensional periodic array of nanoparticles located above ...
Excitation of Propagating Surface Plasmon Using Two-dimensional Array of Ellipsoidal Nanoparticles
In this paper, we investigate the characteristics of a new device for coupling light into symmetric/asymmetric surface plasmon modes on each side of a metallic thin film.
