Droplet impact dynamics on shallow pools

When a fast droplet impacts a pool of the same fluid, a thin ejecta sheet that dominates the early-time dynamics emerges within the first few microseconds. Fluid and impact properties are known to affect its evolution; we experimentally reveal that …

Intersymbol interference for electrophoretic molecular communication in circular duct channels

This letter investigates electrophoretic molecular communication (EMC) operating in circular duct channels. EMC utilizes the time-varying electrophoretic force that can controllably induce the movement of charged particles to enhance communication …

Electrophoretic molecular communication with time-varying electric fields

This article investigates a novel electrophoretic molecular communication mechanism that utilizes a time-varying electric field, which induces time-varying molecule velocities and in turn improves communication performance. For a sinusoidal field, we …
