This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Phononic band gap structures as optimal designs

Jensen, Jakob Søndergaard; Sigmund, Ole

Iutam Symposium on Asymptotics, Singularities and Homogenisation in Problems of Mechanics — 2003, pp. 71-81

In this paper we use topology optimization to design phononic band gap structures. We consider 2D structures subjected to periodic loading and obtain the distribution of two materials with high contrast in material properties that gives the minimal vibrational response of the structure. Both

Systematic design of phononic band-gap materials and structures by topology optimization

Sigmund, Ole; Jensen, Jakob Søndergaard

Philosophical Transactions of the Royal Society London, Series a (mathematical, Physical and Engineering Sciences) — 2003, Volume 361, Issue 1806, pp. 1001-1019

to design and optimize periodic materials and structures exhibiting phononic band gaps. Firstly, we optimize infinitely periodic band-gap materials by maximizing the relative size of the band gaps. Then, finite structures subjected to periodic loading are optimized in order to either minimize the structural
