Over the past century, our understanding of life has been focused on its most fundamental building blocks: molecules. Biological molecules, such as proteins found in blood, other body fluids, or tissues, are excellent guides to identifying a normal or abno ...
In this thesis, the electromagnetic wave propagation is studied in nonstationary-medium scenarios. The electromagnetic fields under material time-modulation are shown to conserve their momentum but not their energy. The mathematical foundations and analysi ...
This paper proposes a simple method to take into account non-vertical risers through an equivalent partial inductance. The proposed approach was validated considering several examples and taking as reference full-wave results obtained using a numerical ele ...
Background: The periodic dielectric multilayers sustaining Bloch surface waves have been proposed as a platformfor the sensing applications and the two dimensional integrated optics. In this paper, we present the experimental and theoretical investigation ...
Harnessing ultrasensitivity from optical structures to detect tiny changes in the targeted samples is the main goal of scientists in the field of sensor design. In this study, an uncommon rhombus-shape plasmonic structure is proposed for providing blue-shi ...
The utilization of subwavelength resonators, such as small electric dipoles, plasmonic resonators, or objects made of materials with a high dielectric constant, has enabled the manipulation of electromagnetic fields down to the subwavelength regime with sy ...
In this article, a rigorous analytical methodology is introduced for designing near-zero refractive index metamaterials (NZIMs). Our proposed NZIM media is realized by three stacked layers of perforated metallic surfaces, each layer composed of a fishnet-l ...
We investigate the invisibility via anomalous localized resonance of a general source in anisotropic media for electromagnetic waves. To this end, we first introduce the concept of doubly complementary media in the electromagnetic setting. These are media ...
The appeal of plasmonics lies in the unique properties of coinage metal nanoparticles to strongly confine and enhance electromagnetic fields at the subwavelength. A simple 50 nm colloidal plasmonic particle can not only break the classical diffraction limi ...
A novel type of a plasmonic sensor based on a magnetophotonic plasmonic heterostructure with an ultrahigh-Q resonance is considered. A magnetoplasmonic resonance with an angular width of 0.06A degrees, which corresponds to a Q factor of 700 and is a record ...
