High Power Microwave (HPM) Devices

Any. GHz thru sub-THz demonstrated in this article

Nonconforming meshes on hexahedral grids are employed with the Discontinuous Galerkin Spectral-Element Time-Domain (DG SETD) method to evaluate the high power microwave breakdown threshold for HPM devices.

Design of complex communications devices employing discontinuous structures that make the devices vulnerable to electric field surges and microwave breakdown.

17.3 CPU seconds DG SETD vs 401.5 CPU seconds SPARK3D for double-ridged waveguide; 11.7 CPU seconds DG SEDT vs. 137.2 CPU seconds SPARK3D for 600 GHz rectangular waveguide coupler; 135.94 CPU seconds DG SETD ve 775.81 CPU seconds SPARK3D for transformer gap filter; 40.69 CPU seconds DG SETD vs 430.94 CPU seconds SPARK3D for S-band ridge waveguide filter.
