Q Factor Enhancement of Open 2D Resonators by Optimal Placement of a Thin Metallic Rod in Front of the Longitudinal Slot

A rigorous approach was employed for the accurate evaluation of the electromagnetic interaction between a thin metallic rod and a two-dimensional (2D) slotted cavity.The problem was posed as a classical boundary value problem for the Helmholtz equation in which a beer button down shirts for men 2D slotted open cavity is bounded by an arbitrary but

The incorporation of wood waste ash as a partial cement replacement material for making structural grade concrete: An overview

With increasing industrialization, the industrial byproducts (wastes) are being accumulated to a large extent, leading to environmental and economic concerns related to their disposal (land filling).Wood ash is the residue produced from the incineration of wood and its products (chips, saw dust, bark) for power generation or other uses.Cement is an
