This model is focused on explaining a lens behavior at the micrometric scale, using its manufacturing parameters. It suggests an approach to predict the solution of the voltage gradient distribution across a microlens. An interesting feature of the model is that it provides an analytical solution for microlenses with modal and hole-patterned electrode schemes, by a simple software tool. The model flexibility allows lens designers to apply complex waveform signals with different harmonics. The voltage distribution has been tested. The simulated and measured voltage profiles are fairly in agreement.Spanish Ministerio de Economia y Competitividad (Grant No. TEC2009-13991-C02-01) and Comunidad de Madrid (Grant No. FACTOTEM S2009/ESP/1781).Publicad
