  • Creeping waves can contribute to the ease of radar detection of a smooth object. Anna Mikhailovskaya and colleagues report here a 3D printed metalized spherical surface patterned with corona virus-like spikes. The structure provides broadband constructive interference between specular reflections and creeping waves elevating the scattering cross-section of the object from all angles.
