Description
Summary:This research article thoroughly explores the electromagnetic behavior in silver metal at optical regime. Along the way, it uncovers some intriguing wave behaviors in terms of novel phenomenon – counterposition, negative phase velocity (NPV), orthogonal phase velocity (OPV) and/or negative refraction (NR), versus wavelength are investigated which is not previously deeply discussed in a silver configuration. Additionally, Minkowski momentum densities, revealing complex wave dynamics versus optical wavelength are studied first time for silver metal. Moreover, the influence on wave in silver metal due to L-nihility is notified fruitfully. These findings provide deeper insights platform for potential applications in diverse scientific and technological domains in condense matter physics, engineering and optics.
