The scattering of electromagnetic radiation from a conductive rectangular plate of infinitesimal thickness covered by a dielectric parallelepiped of arbitrary size is analyzed. An integral equation ...

We apply machine learning (ML) techniques to identify the modes in rectangular waveguides from images of 2D modal field patterns injected with uniform, exponential, correlated exponential, and ...

In several cases, for example, BCD and DPP, morphogens form exponential gradients 14, 15, 17 and are in steady state 17, 18 (Box 1). However, departures from this theme have also been reported 19.
