The packaged microbubble resonators (PMBRs) provide a promising platform for investigating the interaction between fluid and optical microcavity. In this work, PMBRs have been applied to study the ...

Figure 2. Schematic illustration of the water-induced phase separation in the ASD and schematic ternary phase diagram of API/polymer/water for the desired release behavior.

We demonstrated three kinds of broadband terahertz achromatic metasurfaces with linear phase gradients including a deflector, a beam splitter and an axicon, whose phase and dispersion were ...
