Radome design

A radome structure comprising:

• a first syntactic foam layer,
• a multilayer tuning component overlying the first syntactic foam layer and comprising a first tuning sublayer and a second tuning sublayer overlying the first tuning sublayer,
• a structural laminate core overlying and in contact with the multilayer tuning component, and
• a second syntactic foam layer overlying the structural laminate core,
• wherein the first tuning sublayer comprises a dielectric constant (Dk1) of at least about 1 and not greater than about 3,
• wherein the second tuning sublayer comprises a dielectric constant (Dk2) of at least about 1 and not greater than about 3, and
• wherein the multilayer tuning component comprises an average dielectric constant
