The modes are solutions of Maxwell's equations depending on boundary conditions of the waveguide (step-index fiber with 1 n ? n for core and 2 n ? n for cladding). In this paper, the general characteristic equation was deduced. This equation was used

The necessity of studying the influence of the transformation of the frequency mismatch function of a coherent bundle of radio pulses on the quality of solving the radar frequency resolution problem is substantiated. This solution determines the effe

In the free-cutting field, Bi-bearing steel is widely concerned because it supplies the parts for instruments. This work aims to explore the forms of Bi particles existing in 1215MS steel and to detect the effect of Bi on the grain size and thermal e

We develop an intuitive understanding for the various properties and guiding mechanism of M-type fibers. We also report the approximate expression for the V-parameter (normalized frequency) to predict the modal-cutoffs for the M-type fibers, for the

In the present work, the quality factor (and thermoelastic damping) of a microbeam resonator is analyzed by employing the three-phase-lag thermoelasticity theory with memory-dependent derivative. We compare our results with different heat conduction

In this paper, a novel polarization-maintaining highly birefringent photonic crystal fiber (PMHB-PCF) has been investigated by using finite element method (FEM). Initially, the numerical analysis is carried out to ascertain its PMHB characteristics b
