Abstract: When compressing the electric field integral equation with the adaptive cross approximation or related fast solvers, the resulting matrix can often be affected by numerical cancellations at ...
Abstract: We report an adiabatic bend based on silicon shallow-etched waveguide using a sine-circle-sine design. The loss per 180° turn is 0.05 dB for 5 μm bend and 0.008 dB 10 μm bend for TE ...
