or running parameter sweeps and optimizations in parallel), see the corresponding section in the Frequency Domain solver'sAccelerationdialog box, as well as the sectiondistributed computing and adaptive samplingbelow.
The average-derivative optimal scheme for the scalar wave modeling is advantageous in terms of the storage saving for the system of linear equations and the flexibility for arbitrary directional sampling intervals. However, using a LU-decomposition-based direct solver to solve its resulting system of...
During an optimization iteration, the solver first evaluates requirements with this option selected. If the constraint is violated, the solver skips evaluating any remaining requirements and proceeds to the next combination of parameters in the parameter set. If the constraint is not violated, the sol...
sys = ssest(data,nx) estimates a continuous-time state-space model using the time-domain or frequency-domain data in the data object data. Use this syntax especially when you want to estimate a state-space model using frequency-domain or frequency-response data, or when you want to take ...
Next, based on the permittivity function, use the eigensolver to get the numerical waveguide port. # params for domain height = 2 width = 2 len_slab = 0.6 eps0 = 1.0 eps1 = 2.0 eps_numpy = lambda y: np.where( np.logical_and(y > (height - len_slab) / 2, y < (height + ...
This gives the solver flexibility and has proven to lead to very robust results. For this exemplary data, the weighting of the objectives is implemented by empirical values depending on the number of equations associated with each criterion. The goals are defined by a percentage of the ...
For more information about the implementation of a Finite-Difference Frequency-Domain solver, please refer toElectromagnetic and Photonic Simluation for the Beginnerby Raymond C. Rumpf. In general, this section will only discuss three functions found inelectric_funcs.py. ...
a Prediction of the scattering parameter of a single-port antenna structure (against a 3-D electromagnetic finite-element-method solver) embedded in a high-frequency dielectric between 20-40 GHz. b. Prediction of scattering parameters of two-port filter structures between 30-100 GHz realized with...
Electromagnetic and conjugate heat transfer problems can be solved using the commercial FEM solver (COMSOL Multiphysics). The “electromagnetics, beam envelopes” module was used to calculate the heat generated around the nanohole array. The entire simulation domain of the 20 × 20 nanohole array...
“sampling scopes.” After repeated triggers, the points are reassembled according to the sampling algorithm to create a higher “effective” sample rate version of the waveform. Furthermore, the repeated trigger events permit averaging, which can be utilized to increase the signal-to-noise ratio ...
