Having or relating to ten poles or polar regions (a technical term used rarely in physics or mathematics).
From deci- (ten) + polar (relating to poles). This is a constructed technical term following standard scientific naming conventions, though actual usage is extremely rare.
Scientists love making technical words by combining number prefixes with descriptive terms—'decipolar' shows how you can theoretically describe anything with enough poles, even though the Earth stubbornly remains bipolar!
