Abstract:

A simple formalism of the radiative and reflective properties of uniform panels immersed in fluids is reviewed and developed. The formalism is made to accommodate the introduction of passive mechanical layers and active surface drivers designed to control these properties. The passive mechanical layers are defined in terms of lumped surface impedances of panel-like and compliant-like layers. The active surface drivers are applied onto the panel- like layers only. The formalism may be employed to assess the benefits that may accrue using these active andor passive devices. Keywords Radiation, Reflection, Transmission, Layered media, Active and passive controls.
