Symposium on “Surrogate Modeling for High-dimensional Parametric Frequency Domain Problems” (SuMoFreq 2027)
Darmstadt, Germany, 4–5 March 2027
The approximation of the frequency response functions (FRFs) of complex systems has been an active field of research in engineering for decades. Incorporating variable system parameters introduces additional challenges, particularly when high-dimensional parameter spaces interact with strong dynamic variability (e.g., stability preservation, curse of dimensionality, pole tracking and matching). While parametric extensions of established methods – such as Vector Fitting, parametric AAA, the Loewner approach, Model Order Reduction, and data-driven surrogates – show strong promise, scaling these approaches to complex, large-scale industrial applications remains an active and exciting frontier. In this workshop we will bring together experts across different fields, such as electrical engineering, mechanical engineering, applied mathematics and computational sciences to discuss recent developments and advances and the challenges of translating advanced mathematical methods into real-world benchmarks and industrial application. The workshop will have an informal character and provide sufficient time for exchange and scientific discussion. Topics include, but are not limited to:
- High-dimensional parametric FRFs & multivariate rational approximation
- Parametric interpolation & model order reduction / low-rank methods
- Stability, causality, and passivity preservation in surrogate modeling
- Uncertainty Quantification (UQ) and sensitivity analysis in simulation workflows
- Kernel/Gaussian process and machine learning surrogates
- Applications in electromagnetic compatibility, microwave engineering, vibroacoustics, operational modal analysis, structural health monitoring and others
Participation is free (i.e. no registration fees apply).

Contributions
There are two kinds of contributions to the symposium possible from your side:
- Presentations in the plenary sessions (30min, including 10min of discussion)
- Posters in a corresponding session (poster size at least DIN A1)
To ensure a balanced and cohesive programme, the organising committee reserves the right to propose a presentation format (oral or poster) for all accepted abstracts.
Abstracts for both types of contributions may be sent to sumofreq27@ce.tu-… as emails or with a plain text attachment. If your abstract includes any figures or formulas you may send your LaTeX source including the corresponding image files (plus a PDF file such that we know your intended layout). Just use the generic article class for your abstract with as few additional packages as possible.
Each abstract should contain the following data and have a maximum length of one page (DIN A4):
- Type of contribution (presentation or poster)
- Title
- Name(s) of author(s), including affiliation(s)
- Summary (max. 2,500 characters incl. whitespaces)
Important dates
- Begin of registration: 1 October 2026
- Deadline for submission of abstracts: 30 November 2026
- Notification of acceptance: 12 January 2027
Location
TU Darmstadt, Friedrich Ludwig Weidig Saal (S3|20-18), Rundeturmstraße 10, 64289 Darmstadt
Accommodation
