Unfortunately, the results obtained by such models are very sensitive to the value used for the dielectric constant. Furthermore, the factors that determine the optimal value of these constants are far from being obvious. This review considers the meaning of the protein dielectric constants and the...

The thickness of the copper along with the dielectric constant (dk or e sub r) of the material are two primary factors in determining the trace geometry. Exotic materials are known for their thermal stability, their tight control over the dk and for a low loss tangent. Those properties come...
The copper foils at both side of the polymeric film were used as the electrodes and the dielectric constant and dielectric loss of the samples were measured at temperature from 100 Hz to 200 kHz. Dielectric Properties of Azo Polymers: Effect of the Push-Pull Azo Chromophores The dielectric cons...
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...
Due to the parasitic effects mentioned earlier, you will need to carefully select asubstrate materialand design your stackup. Thedielectric constantof your substrate will affect the geometry required to produce a transmission line with specific impedance and will affect the impedance of the po...
The dimensions of the trace which includes trace thickness andtrace width, dielectric thickness of thePCB material, and the dielectric constant determine the impedance of a trace. The trace impedance is usually within the range of 25 and 125 Ohms. Below are factors that affect the impedance of ...
How to find the wavelength of a photon What causes the bending of light in refraction? How to calculate energy of a photon How to calculate the dielectric constant of water The speed of light in an unknown medium is measured to be 2.76 x 10^8 m/s. What is the index of refraction of...
Dielectric Constant (Dk): A material's dielectric constant (Dk) determines the speed at which electromagnetic signals travel through it. When selecting materials for high-frequency PCBs, you'll want to choose those with a low Dk. This ensures signals propagate at the desired velocity, minimizing...
The substrate often consists of a glass weave, epoxy, or paper resin, depending on the dielectric constant. On the other hand, laminates consist of cloths or paper layers. These materials not only affect the structure of the board but also the overall thickness. ...
