Data associated with "Characterizing the broadband RF permittivity of 3D-integrated layers in a glass wafer stack from 100 MHz to 30 GHz" for the 2024 International Microwave Symposium (IMS) in Washington, D.C.

Data provided by  National Institute of Standards and Technology

We present a method for accurately determining the permittivity of dielectric materials in 3D integrated structures at broadband RF frequencies. With applications of microwave and millimeter-wave electronics on the rise, reliable methods for measuring the electrical properties of dielectrics used in integrated circuits are critical. We outline an on-wafer method for extracting the permittivity of a 3D multilayer glass structure from 100 MHz to 30 GHz using S-parameter measurements of different calibration chips.

Smart network repository based on Neo4j native graph database

Data provided by  National Institute of Standards and Technology

To address the increasing complexity of network management and the limitations of data repositories in handling the various network operational data, this paper proposes a novel repository design that uniformly represents network operational data while allowing for a multiple abstractions access to the information. This smart repository simplifies network management functions by enabling network verification directly within the repository.

Data associated with "Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment"

Data provided by  National Institute of Standards and Technology

Data associated with the publication: "Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment"Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In the corresponding paper, we provide a theoretical understanding of EIT signals in the presence of a large magnetic field, as well as demonstrate some advantages of this technique over traditional Autler-Townes based electrometry.

2022 American Community Survey: 5-Year Estimates - Public Use Microdata Sample

Data provided by  United States Census Bureau

The American Community Survey (ACS) Public Use Microdata Sample (PUMS) contains a sample of responses to the ACS. The ACS PUMS dataset includes variables for nearly every question on the survey, as well as many new variables that were derived after the fact from multiple survey responses (such as poverty status).Each record in the file represents a single person, or, in the household-level dataset, a single housing unit. In the person-level file, individuals are organized into households, making possible the study of people within the contexts of their families and other household members.

2022 American Community Survey: 5-Year Estimates - Public Use Microdata Sample Puerto Rico

Data provided by  United States Census Bureau

The Public Use Microdata Sample (PUMS) for Puerto Rico (PR) contains a sample of responses to the Puerto Rico Community Survey (PRCS). The PRCS is similar to, but separate from, the American Community Survey (ACS). The PRCS collects data about the population and housing units in Puerto Rico. Puerto Rico data is not included in the national PUMS files. It is published as a state equivalent file and has a State FIPS code of "72".
