← ScienceWhich safety risk during radar operation rises due to high-power electromagnetic wave propagation?
A)Localized tissue heating by dielectric absorption✓
B)Internal arcing within resonant cavities
C)Increased waveguide reflective power losses
D)Antenna array element structural deformation
💡 Explanation
Dielectric absorption causes internal heating, because energy transfer efficiency depends on the frequency. Therefore, tissue damage is the answer, rather than internal arcing, which typically happens due to high voltage breakdown under vacuum or impedance mismatches.
