By Kenneth Wyatt INTRODUCTION One tool every EMC test lab should own is a harmonic comb generator. A comb generator is simply a device that will produce a set of harmonically related CW signals whose spacing is based on a fundamental oscillator frequency. For example, if we were to start with a 10 MHz clock oscillator and feed the digital output into a coax connector, we’d … [Read more...]
Tech Tidbit: Gwyneth Paltrow has ‘Golden Halo’ in Electromagnetic Image of Aura
Gwyneth Paltrow, a well-known actress, recently had her “aura read” and posted an image of it on her blog ‘Goop.’ The picture was taken by Christina Lonsdale using a rare camera invented in 1970 for the sole purpose of capturing people’s auras. Electromagnetic fields that surround our bodies, also known as auras, are normally invisible; however, they can be illuminated with … [Read more...]
