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 omnidirectional on-chip electromagnetic-thermal cloak is proposed. Firstly. https://www.ashleyshomestores.shop/product-category/rect-drm-counter-tbl-set3-cn/
