A Low-Latency, Low-Power CMOS Sun Sensor for Attitude Calculation Using Photovoltaic Regime and On-Chip Centroid Computation
(Institute of Electrical and Electronics Engineers, 2023)
The demand for sun sensors has skyrocketed in the last years due to the huge expected deployment of satellites associated with the New Space concept. Sun sensors compute the position of the sun relative to the observer and ...

Spatial angular filtering by FSSs made of chains of interconnected SRRs and CSRRs
(Institute of Electrical and Electronics Engineers, 2013)
Two frequency selective surfaces (FSSs) made of an infinite set of parallel 1-D chains of interconnected split ring resonators (I-SRRs) and interconnected complementary split ring resonators (I-CSRRs) are studied. The main ...

Simple and compact balanced bandpass filters based on magnetically coupled resonators
(Institute of Electrical and Electronics Engineers, 2015)
A simple strategy is proposed to design differential-mode bandpass filters with good common-mode (CM) rejection using simple resonators. Specifically, the CM rejection is enhanced by using conventional open-loop resonators ...

Characterization of miniaturized metamaterial resonators coupled to planar transmission lines through parameter extraction
(AIP Publishing, 2008)
In this paper, a method for obtaining the electrical characteristics of metamaterial resonators coupled to planar transmission lines is proposed. This parameter extraction technique is based on the comparison between the ...

Pull-off force of coated fine powders under small consolidation
(American Physical Society, 2009)
In this paper, a three-dimensional model taking into account the contact deformation and surface area coverage (SAC) of nanoadditives is proposed to predict the force required to separate two contacting particles (the ...

Post-quantum biometric authentication based on homomorphic encryption and classic McEliece
(MDPI, 2023-01)
Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric data, to be compared in a protected way, revealing only the comparison result when the private key is known. This is very useful ...

Two-dimensional numerical analysis of electroconvection in a dielectric liquid subjected to strong unipolar injection
(American Institute of Physics, 2012)
Two-dimensional numerical simulations are carried out to examine the problem of transient electroconvection stability of dielectric liquids subjected to unipolar injection. The entire set of electrohydrodynamics equations ...

Non-Fungible Tokens Based on ERC-4519 for the Rental of Smart Homes
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The rental of houses is a common economic activity. However, there are many inconveniences that arise when renting a property. The lack of trust between the landlord and the tenant due to fraud or squatters makes it necessary ...

Droplet group production in an AC electro- flow focusing microdevice
(Springer, 2017-09)
We report the production of droplet groups with a controlled number of drops in a microfluidic electro-flow focusing device under the action of an AC electric field. This regime appears for moderate voltages (500-700 V ...
