Over a hundred years later, the classic antenna, first invented by Heinrich Hertz, in 1888, [1], is still the dominant technology used for the measurement of RF fields. Just seven years after its invention, Guglielmo Marconi applied the antenna to long

During laser powder bed fusion additive manufacturing, a protean pool of molten metal governs a complex energy absorption process as it presents as either a highly reflective surface, a deeply absorbing cavity (a keyhole), or some amalgamation thereof. To
