Modular educational wave kit: Plug and play 3D printable sine waves The plug and play 3D printable sine waves are a simple but effective teaching aid which helps the students to understand wave properties better. They get to try for themselves how wave properties like constructive and destructive interference work. Further they get to explore the interdependence of the wavelengths and diffraction angles, the distances between the slits and the distances from the slits to the observation screen. This way, the famous single and double slit experiments, as well as the diffraction grating and its equation can be understood in an handson manner that does not require any animations, as it is interactive by its playful nature. Further use of the same kit or a slightly modified version could include but would not be limited to: the modelling of water, pressure and all kinds of electromagnetic waves, all kinds of waves in general.

High capacity photonic beamforming for phased antennas Phased array antennas are suitable for massive MIMO wireless communications, of which 5G and satellite communications are paradigmatic examples. These 2 patent families propose a photonic beamforming system that is able to process a large number of RF signals with a very broad bandwidth, something that cannot be done with digital processors. The proposed photonic beamformer is thus a key enabler for broadband massive MIMO wireless communications.

Passive sensor system powered by wireless power transmission Network of wireless and passive sensors (without batteries), using a set of unique sensors which use a frequency for the data transfer (obtained by sensors) and another frequency for the reception of energy that is emitted by transmitters that power the sensors. For this, only a central data reception and wireless transmission structure is required which communicates with each of the sensors independently. These sensors have low power consumption and high data rates (up to 960 Mb/s).

Reconfigurable beam reflectarray antenna for frequencies in the range of terahertz and millimeter wave The reflectarray antenna consists of a flat array of phase-shifter cells (reflectarray) illuminated by a feeder, which produces an electronically reconfigurable collimated or shaped beam, where the cells (3b) consist of several stacked layers of conductive elements (4c, 4e, 4d, 4f) on a dielectric substrate (7c, 7d) alternated with layers of liquid crystal (5c, 5d) and a conductive plane (9). Applying bias voltages in the conducting elements, the dielectric constant of the liquid crystal varies producing a phase shift of the reflected field in each cell, allowing for a electronic beam scanning or reconfiguration. Including multiple layers of conductive elements and liquid crystal, improves the bandwidth and the performance of the beam scanning or reconfiguration. The antenna can be applied to observation satellites, communications and security systems.

New FFTH-PON Network for extended numbers of users A new Passive-Optical-Network (PON) for Fiber-To-The-Home (FTTH) services has been developed in the frame of the National Research Project TEYDE. While current FTTH networks as GPON and EPON can reach a maximum of 32-64 users, the proposed PON can serve more than 4000 users, thanks to a new device for distributing the signal among the users that intelligently recycles the noise generated by other elements of the network. Partners to further develop the device and/or to establish license agreements with technical cooperation are sought.
