Applications/Examples of results
◆Examples of Applications for Electromagnetic Wave Absorbers ◆What is Electromagnetic Wave Absorption? Q How do electromagnetic waves propagate through space? Q How do electromagnetic waves reflect at interfaces? In the cases of TE waves, TM waves, and circularly polarized waves. Q What happens to reflection, absorption, and transmission when electromagnetic waves incident on a material? Q How do materials absorb electromagnetic waves? Q What is the difference between electromagnetic wave absorption and electromagnetic wave shielding? Q What is an inclined (dielectric) electromagnetic wave absorber? Q What is a conductive electromagnetic wave absorber? ◆What is the design of electromagnetic wave absorbers used in space (far field, near field)? Q How are material constants measured? Using the coaxial waveguide method (400MHz to 23GHz) as an example. Q Why is reference measurement in the coaxial waveguide method important, and how is air measured? Q How are the dielectric constant and permeability of Teflon measured? As a reference material. Q What is the measurement of material constants using the space method (up to 110GHz)? Using alumina as an example. Q What is the measurement method for thin film electromagnetic wave absorbers (sheets)? Q What are the methods for measuring internal coupling loss, mutual coupling loss, transmission coupling loss, and radiation suppression rate? ◆What is the design of electromagnetic wave absorbers for ETC? (Far field) Q How are rubber (EPDM) and magnetic (iron powder) and dielectric (titanium oxide) composites made?
