A heptagonal photonic crystal fiber-based oil sensor is proposed and numerically
investigated in this paper in order to detect the adulteration of petrol with kerosene using …

A fabricated microstructured polymer optical fiber (MPOF), with porous core and porous
cladding consisting of a hexagonal array of circular air-holes, is experimentally investigated …

Fuel quality has a significant impact on the lifespan and smooth operation of petroleum
engines. Many dishonest merchants mix lower priced oil/ingredients with petroleum …

Hexagonal porous optical fiber without a central defect is proposed and numerically
analyzed with the finite element method (FEM) for transmitting terahertz (THz) …

This chapter labels the recent advances of terahertz (THz or 10 12 Hz) technology-based
image processing and its applications. In short, the sandwiched regime between infrared …

Terahertz (THz) radiation has been noted to affect biological organisms to a unique degree
with various effects ranging from modifications brought to protein activity to epigenetic …

This work reports some important optical characteristics of porous core photonic crystal fiber
(PC-PCF) for four different core structures which are elliptical, circular, square, and …

A method for creating of a three-dimensional nonlinear optical grating based on the
alternation of layers with different nonlinear optical properties has been developed. The …

A new type of anti-resonant hollow-core fiber for terahertz waveguides is proposed. By
introducing central support pillars and an elliptical structure, the fiber achieves high …

Negative curvature fibers have the benefits of high bandwidth, low loss, and provide higher
transmission performances. Birefringence of the fiber is particularly important, with potential …
