Ray tracing, taking reflection and diffraction into account, is employed together with asymptotic techniques for electromagnetic analysis of large and complex objects. This paper introduces a novel approach in numerical ray tracing providing analytical models for ray congruences in the presence of ...

attention is here being called to self-consistent hybrid ray-mode and wavefront-resonance techniques — originally introduced in electromagnetics and underwater acoustics, and more recently in seismology — which incorporate a new approach to the multiwave, multilayer problem and the scattering problem,...
The resultant impedance mismatch will cause a slight reflection at the interfaces, which can be suppressed by practical antireflection techniques and thus is not considered here. Therefore, the cloak can be implemented with glass (e1 ¼ 1.832) and air (e2 ¼ 1) with a background of water ...
Existing threshold selection techniques in multi-threshold image segmentation, such as Kapur based on exhaustive enumeration, often hamper efficiency and accuracy. The whale optimization algorithm (WOA) has shown promise in addressing this challenge, but issues persist, including poor stability, low ...

Adding other selection techniques and criteria to select more accurate individuals has become increasingly common. Similarly, the FW algorithm in this article also added distance metrics. With only a single fitness evaluation, it is easy to find a local solution. The introduction of distance metrics...
