Summary: Simultaneously guiding electromagnetic waves and heat flow at any incidence angle to smoothly bypass some electromagnetic/thermal sensitive elements is a key factor to ensure efficient communication and thermal protection for an on-chip system.In this study, an st albans alpaca scarf omnidirectional on-chip electromagnetic-thermal cloak is proposed.Firstly, a holey metallic plate with periodic array of subwavelength apertures is designed by optical surface transformation to realize an omnidirectional electromagnetic cloaking module for on-chip electromagnetic signal.
Secondly, a two-layer ring-shaped engineered thermal structure is designed by solving Laplace equation to realize an hlpro4sw omnidirectional thermal cloaking module for in-chip heat flow.Finally, these two cloaking modules are combined to achieve cloaking effect for both the electromagnetic waves and thermal fields simultaneously, thus protecting the build-in electromagnetic/thermal sensitive elements without disturbing the external fields.The proposed electromagnetic-thermal cloak may have potential advantage in dealing with omnidirectional electromagnetic compatibility/shielding and multi-directional thermal management/dissipation of an on-chip system.
