InCa3D is a simulation tool dedicated to electrical connection modelling for both: . Electromagnetic compatibility [1] [2]; Power electronics; The software employs finite element analysis based on the PEEC Partial element equivalent circuit method [3] which proved to be efficient to solve Maxwell's equations in low and middle frequency, thanks to its ability to convert interconnections ...

RLC circuit as a parallel band-stop filter in series with the line
An important parameter when discussing band-pass filters is the fractional bandwidth. This is defined as the ratio of the bandwidth to the geometric centre frequency. The inverse of this quantity is called the Q-factor, Q. If ω 1 and ω 2 are the frequencies of the passband edges, then: [53]
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
An RLC circuit can be used as a band-pass filter, band-stop filter, low-pass filter or high-pass filter. The tuning application, for instance, is an example of band-pass filtering . The RLC filter is described as a second-order circuit, meaning that any voltage or current in the circuit can be described by a second-order differential equation ...
The accuracy depends on both filter structure and resonator structure. The accuracy improves when the fractional bandwidth narrows. Inaccuracy of formulas (16) and their refined version is caused by the frequency dispersion of the coupling coefficients that may varies in a great degree for different structures of resonators and filters.

The fractional bandwidth of an LC circuit is given by, B = m − 1 Q {\displaystyle B={{\sqrt {m-1}} \over Q}} where m is the power ratio of the power at resonance to that at the band edge frequency (equal to 2 for the 3 dB point and 1.19 for the 0.75 dB point) and Q is the quality factor .
