Implicit models for evaluation of electrostatic energies in proteins include dielectric constants that represent effect of the protein environment. Unfortunately, the results obtained by such models are very sensitive to the value used for the dielectric constant. Furthermore, the factors that determine ...
The term dielectric constant refers to the property of a material to withstand external electric fields without changing its conductance value. The dielectric constant is a quite important parameter for ceramic and metal oxide materials that are used in various electronic systems in order to control a...
Our calculations for complex graphene RI used the Vienna Ab-initio Simulation Package (VASP) to determine the dielectric constants for both the in-plane (xx) and cross-plane (zz) directions (Fig. 7). Then, the complex RI value of graphene can be readily obtained by taking a square root ...

to be considered. It is necessary to determine and consider the acceptable range (tolerance) of impedance during the design phase and when specifying PCB parameters. In many cases, it is sufficient to use a software model to determine the expected impedance for a specific dielectric material and...
(TOP). The key variable in radar technology is the dielectric contact of liquid. The reason is that the amount of reflected energy at microwave (radar) frequencies is dependent on the dielectric constant of the fluid, and if Er is low, most of the radar’s energy enters or passes through...
The difficulty is linked to the effective dielectric constant (εr_eff) calculation for a given substrate. A 2.5/3D field-solver software is often used to determine εr_eff. PCB manufacturers can assist greatly in this task. Whenever possible, ask to the PCB manufacturer for the design rules...
Use calculators or equations to determine single-ended or differential pair impedances based on dielectric constant, trace dimensions, and reference planes. Q: What PCB finishes provide the best high frequency signal integrity? Immersion silver and annealed copper (oxidation resistant) offer minimal skin...
This proficiency is evident in the interpretation of properties like “dielectric constant” and “dielectric loss” as demonstrated in Figs. 15 and 16. 2. Recognition of units of the properties: LLMs can recognize dimensionless nature without explicit mention in the table and correctly find the...
