This video shows the definition of the goal function for the optimization of microwave filters with a Generalized Chebyshev response. To define the goal in InventSim, we use the module for coupling matrix synthesis.

Advanced optimization example of narrowband, 6th order dielectric resonator filter with two transmission zeros using InventSim – a 3D FEM electromagnetic solver. Passband 2.164GHz – 2.176GHz, zeros at 2.162GHz and 2.163GHz. 17 optimization variables (design parameters). Total optimization time 69 minutes (video speed up x10). Design based on: S. Bastioli and R. V. Snyder, „Inline Pseudoelliptic${\rm TE}_{01\delta}$-Mode Dielectric Resonator Filters Using Multiple Evanescent Modes to Selectively Bypass Orthogonal Resonators,” in IEEE Transactions on Microwave Theory and Techniques, vol. 60, no. 12, pp. 3988-4001, Dec. 2012.

The video shows a sample simulation of a combline diplexer for the GSM band with adaptive mesh refinement and fast frequency sweep.

This video shows the interactive tuning feature of InventSim 3D FEM electromagnetic solver.

Simulation example of dual-band Wilkinson power divider shows how to include lumped elements in EM simulation with InventSim.

Design based on: F. Liu and J. Lee, „Design of New Dual-Band Wilkinson Power Dividers With Simple Structure and Wide Isolation,” in IEEE Transactions on Microwave Theory and Techniques, vol. 67, no. 9, pp. 3628-3635, Sept. 2019

This video shows how to draw a basic 3rd-order microwave combline filter. The structure is parameterized with design variables, that can be further optimized to get the desired filtering response.

This video shows how complex volumes can be drawn using B-spline curves. The 1D contour is transformed into a 2D face and then extruded into a 3D object.

This video shows an example of a simple Python script using the InventSim COM Interface. Example script performs a parametric sweep of the width of a microstrip line in the design of a simple impedance transformer.
