Measurements monitoring the inductive coupling between oscillating radio-frequency magnetic fields and objects of interest create versatile platforms for non-destructive testing. The benefits of ultra-low-frequency measurements, i.e., below 3 kHz, ar

Efficient all-optical poling of an azo-dye copolymer (consisting of a PMMA backbone to which DR1 molecules were grafted as pendant side groups) using a low power microsecond laser is demonstrated. Conversion efficiencies are as large as those usually
