MM-Wave beam scanning and imaging array technology

The novel microfluidic reconfiguration technique introduced by USF researchers alleviates the need for active RF switching devices by utilizing antenna elements consisting of liquid metals or metalized plates movable within interconnected microfluidic channels placed at the focal surfaces of microwave lenses. The flexible nature of the microfluidic channels also offers a convenient method for curved surface installations to realize wide-field-of-view performance. They also allow for realizing high-resolution mm-wave imaging arrays that can be used in a variety of applications such as medical or structural health monitoring. Consequently, this novel microfluidic reconfiguration approach holds potential to transform high-data rate communication, surveillance, and imaging systems into mainstream technologies by offering unparalleled flexibilities at a fraction of the cost of traditional solutions. The invention can be widely used in commercial millimeter-wave applications such as satellite communications and microwave imaging. It also can be utilized for military and meteorology applications.
