Here, we report the mapping of optical modes in a waveguide structure by illumination with femtosecond light pulses in a continuous-beam transmission electron microscope. Multiphoton photoemission ...

Abstract: This paper describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that: (1) gives a semi-analytical ...

A recently shared brain teaser has grabbed internet's attention, leaving users puzzled and eager to crack the code ... it’s all about finding the pattern. This particular brain teaser has ...
