摘　　要：The wide field-of-view(FOV) optical receiver has many advantages in optical wireless communication,sensing and detection.However,the FOV is limited by some tradeoffs of the receiver's components employing conventional optical devices.Furthermore,present mechanisms to extend the FOV are not effective.To realize the wide FOV receiver effectively,we propose surface plasmon polaritons(SPPs) as the potential candidate.Two examples are presented to lively illustrate SPPs' striking power to offer unexpected solutions to conventional problems.It is shown that unusual conditions should be explored to make use of SPPs under some circumstances.Excitations of localized SPPs,which are independent of the incidence angle,are suggested as the mechanism for the wide FOV receiver.Some progress in the optimization of SPPs' excitation at oblique incidence is also reported.The wide field-of-view （FOV） optical receiver has many advantages in optical wireless communication, sensing and detection.

Two examples are presented to lively illustrate SPPs＇ striking power to offer unexpected solutions to conventional problems. It is shown that unusual conditions should be explored to make use of SPPs under some circumstances. Excitations of localized SPPs, which are independent of the incidence angle, are suggested as the mechanism for the wide FOV receiver. Some progress in the optimization of SPPs＇ excitation at oblique incidence is also reported.
