Two parallel plates are temperatures T1 and T2 and have emissivities of ε1 = 0.8 andε2= 0.5. A radiation shield having the same emissivity ε3 on both sides is placed between the plates. Calculate the emissivity ε3 of the shield in order to reduce the radiation loss from the system to one-tenth of that without the shield.
