The invention discloses an electromagnetic energy adaptation material, which can absorb electromagnetic energy, the material including a mixture of at least one liquid with at least one surfactant. The liquid may be a dipolar molecular liquid, and may be pressurized by means of a gas. Further the use of an electromagnetic energy adaptation material in the form of a foam for covering an object to prevent detection thereof by an electromagnetic energy detection apparatus, such as radar equipment, is disclosed. Finally a method of minimizing or altering detection of an object by means of electromagnetic energy detection apparatus is suggested, which includes the steps of coating such an object or a zone spaced away from such an object at least partially by means of a foam of an electromagnetic energy adaptation material.
