Almost all high-voltage dc generation for low-power applications is done by either electrostatic machines or voltage multipliers. Electrostatic machines use mechanically moving parts to transfer charge and energy from the low-voltage side…
Electro-optic (EO) modulators rely on interaction of optical and electrical signals with second-order nonlinear media. For the optical signal, this interaction can be strongly enhanced by using dielectric slot-waveguide structures that…

It has been found that some text-books show LC-oscillators that may not work as assumed. Thus, the typical example showing a LC-oscillator driven by a voltage operational-amplifier is simply wrong. The difficulty stems from the fact that…
