Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

Advanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Planar reconfigurable antennas

2006 First European Conference on Antennas and Propagation, 2006
In this paper it is shown that planar reconfigurable antennas can cover a wide range of designs such as fractal antennas, triangular antennas, monopole, dipoles, log-periodic etc. Some of these designs can also be used to yield tunable electrically small antennas for miniature wireless device applications.

Planar Triorthogonal Diversity Slot Antenna

IEEE Transactions on Antennas and Propagation, 2017
This communication proposes an easily manufacturable multifunction multiport planar slot antenna with triorthogonal pattern diversity. Distinct radiation patterns are emitted via a common square radiative slot by exploiting three orthogonal modes. These slot modes consist of a magnetic current loop mode with an omnidirectional linearly polarized (OLP ...
