The coupled normal mode method is a powerful approach for solving range-dependent propagation problems in underwater acoustics. An important area of study is to improve stability and efficiency so as ...

Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.
