Data fr paper: Confinement of surface waves at the air-water interface to control aerosol size and dispersity. File 1: Capillary wave.xlsx Contains 1 - wavelength measurements at the air-water surface for free sessile drop of various volumes (Figure 2a). 2 - wavelength measurements at the air-water surface for confined liquid in cavities (Figure 2 b&c). 3 - wavelength measurements at the air-water surface for 2ul sessile drop at various input power (Figure 3a). 4 - wavelength measurements at the air-water surface for confined liquid in varous cavities and different input power (Figure 3b&c). File 2: Aerosol Droplet size Contains: 1 - Droplet size distribution for nebulisation of free sessile droplet and liquid confined in different cavities (Figure 6a) 2 - Average median droplet size of different measurement (Figure 6b)
