Relativistic-microwave theory of ball lightning. [PDF]
Sci Rep, 2016 AbstractBall lightning, a fireball sometimes observed during lightnings, has remained unexplained. Here we present a comprehensive theory for the phenomenon: At the tip of a lightning stroke reaching the ground, a relativistic electron bunch can be produced, which in turn excites intense microwave radiation.

An Insight on the Microwave Circulator Theory
IEEE AccessThis contribution is devoted to clarifying the analytical derivation of the microwave circulator matrixes. Although this topic seems well-acknowledged, the approach of many books is affected by an initial error that, in turn, affects the final result. It

Designing the response-spectra of microwave metasurfaces: theory and experiments [PDF]
NanophotonicsMetasurfaces composed by arrays of coupled plasmonic resonators have attracted tremendous attention due to their extraordinary abilities to manipulate electromagnetic (EM) waves. However, existing theories for such systems are either empirical with model
